Organization Consolidation And Presentation Of Financial Statements [Abstract] | |
Basis of Presentation | Business Description Airgain, Inc. (the Company) was incorporated in the State of California on March 20, 1995; and reincorporated in the State of Delaware on August 15, 2016. The Company is a leading provider of advanced antenna technologies used to enable high performance wireless networking across a broad range of markets, including consumer, enterprise and automotive. The Company designs, develops, and engineers its antenna products for original equipment and design manufacturers worldwide. The Company’s headquarters is in San Diego, California with office space and research, design and test facilities in the United States, United Kingdom, and China. Basis of Presentation The accompanying unaudited condensed financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) and applicable rules and regulations of the Securities and Exchange Commission (SEC) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Interim financial results are not necessarily indicative of results anticipated for the full year. As such, the information included in this quarterly report on Form 10-Q should be read in conjunction with the financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2018, from which the balance sheet information herein was derived. The unaudited condensed balance sheet as of December 31, 2018, included herein was derived from the audited financial statements as of that date but does not include all disclosures including notes required by GAAP. The unaudited condensed statements of operations for the three and nine months ended September 30, 2019 and 2018, and the balance sheet data as of September 30, 2019, have been prepared on the same basis as the audited financial statements. In the opinion of management, the accompanying unaudited condensed financial statements reflect all adjustments, consisting of normal and recurring adjustments, necessary for a fair presentation of results of the Company’s operations and financial position for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full year ending December 31, 2019, or for any future period. Segment Information The Company’s operations are located primarily in the United States and most of its assets are located in San Diego, California and Scottsdale, Arizona. The Company operates in one segment related to the sale of antenna products. The Company’s chief operating decision-maker is its chief executive officer, who reviews operating results on an aggregate basis and manages the Company’s operations as a single operating segment. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include valuation of intangible assets and goodwill. Reclassifications Certain amounts in the prior period financial statements have been reclassified to conform to the presentation of the current period financial statements. Fair Value Measurements The carrying values of the Company’s financial instruments, including cash and cash equivalents, trade accounts receivable, accounts payable, and accrued liabilities approximate their fair values due to the short maturity of these instruments. Fair value measurements are market-based measurements, not entity-specific measurements. Therefore, fair value measurements are determined based on the assumptions that market participants would use in pricing the asset or liability. The Company follows a three-level hierarchy to prioritize the inputs used in the valuation techniques to derive fair values. The basis for fair value measurements for each level within the hierarchy is described below: • Level 1: Quoted prices in active markets for identical assets or liabilities. • Level 2: Quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs are observable in active markets. • Level 3: Valuations derived from valuation techniques in which one or more significant inputs are unobservable in active markets. Cash Equivalents and Short-Term Investments Cash equivalents are comprised of short-term, highly liquid investments with maturities of 90 days or less at the date of purchase. Short-term investments consist predominantly of commercial paper, corporate debt securities, U.S. Treasury securities and asset backed securities. The Company classifies short-term investments based on the facts and circumstances surrounding the investments at the time of purchase and evaluates such classification as of each balance sheet date. All short-term investments are classified as available-for-sale securities as of September 30, 2019, and are recorded at estimated fair value. Unrealized gains and losses for available-for-sale securities are included in accumulated other comprehensive income (loss), a component of stockholders’ equity. Realized gains and losses are included in other income, in the unaudited condensed statements of operations. The Company evaluates its investments to determine whether those with unrealized loss positions are other than temporarily impaired. Impairments are considered to be other than temporary if they are related to deterioration in credit risk or if it is likely that the Company will sell the securities before recovery of their cost basis. Inventory The majority of the Company’s products are manufactured by third parties that retain ownership of the inventory until title is transferred to the customer at the shipping point. In certain instances, shipping terms are delivery at place and the Company is responsible for arranging transportation and delivery of goods ready for unloading at the named place. The Company bears all risk involved in bringing the goods to the named place and records the related inventory in transit to the customer as inventory on the accompanying balance sheet. The Company also manufactures certain of its products at its facility located in Scottsdale, Arizona. Inventory is stated at the lower of cost or net realizable value. For items manufactured by the Company, cost is determined using the weighted average cost method. For items manufactured by third parties, cost is determined using the first-in, first-out (FIFO) method. Any adjustments to reduce the cost of inventories to their net realizable value are recognized in earnings in the current period. As of September 30, 2019, the Company’s inventories consist primarily of raw materials. Provisions for excess and obsolete inventories are estimated based on product life cycles, quality issues, and historical experience. As of September 30, 2019, there is no provision for excess and obsolete inventories. Accumulated Other Comprehensive Income (Loss) Comprehensive income (loss) is comprised of net income (loss) and other comprehensive income (loss). Accumulated other comprehensive income (loss) on the unaudited condensed balance sheet at September 30, 2019, includes unrealized gains and losses on the Company’s available-for-sale securities. |

Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | Note 2. Summary of Significant Accounting Policies During the three and nine months ended September 30, 2019, there have been no material changes to the Company’s significant accounting policies as described in the Annual Report on Form 10-K for the fiscal year ended December 31, 2018. Recent Accounting Pronouncements In August 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2018-15, Intangibles – Goodwill and Other – Internal-Use Software In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill Impairment , which simplifies the test for goodwill impairment by removing Step 2 which requires a hypothetical purchase price allocation and may require the services of valuation experts. An entity will, therefore, perform the goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount, recognizing an impairment charge for the amount by which the carrying amount exceeds the fair value, not to exceed the total amount of goodwill allocated to the reporting unit. An entity still has the option to perform a qualitative assessment to determine if the quantitative impairment test is necessary. ASU 2017-04 will be effective for the Company in annual periods beginning after December 15, 2020, and interim periods within fiscal years beginning after December 15, 2021, with early adoption permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company has not yet determined whether it will early adopt ASU 2017-04 and is evaluating the impact the standard will have on its ongoing financial reporting. In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments In May 2019, the FASB issued ASU 2019-05, Financial Instruments-Credit Losses (Topic 326), Targeted Transition Relief |

Earnings Per Share [Abstract] | |
Net Income (Loss) Per Share | No te 3. Net Income (Loss) Per Share Basic net income (loss) per share is calculated by dividing net income (loss) by the weighted average shares of common stock outstanding for the period. Diluted net income (loss) per share is calculated by dividing net income (loss) by the weighted average shares of common stock outstanding for the period plus amounts representing the dilutive effect of securities that are convertible into common stock. The Company calculates diluted income (loss) per common share using the treasury stock method and the as-if-converted method, as applicable. The following table presents the computation of net income (loss) per share (in thousands except per share data) Three Months Ended September 30, Nine Months Ended September 30, 2019 2018 2019 2018 Numerator: Net income (loss) $ (135 ) $ 437 $ 863 $ (3,858 ) Denominator: Weighted average common shares outstanding - basic 9,711 9,566 9,678 9,495 Plus dilutive effect of potential common shares — 527 405 — Weighted average common shares outstanding - diluted 9,711 10,093 10,083 9,495 Net income (loss) per share: Basic $ (0.01 ) $ 0.05 $ 0.09 $ (0.41 ) Diluted $ (0.01 ) $ 0.04 $ 0.09 $ (0.41 ) Diluted weighted average common shares outstanding for the nine months ended September 30, 2019, includes 3,000 warrants and 402,000 options outstanding.

(2) Level 2 fair value estimates are based on observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. The Company’s investments were primarily valued based upon one or more valuations reported by its investment accounting and reporting service provider. The investment service provider values the securities using a hierarchical security pricing model that relies primarily on valuations provided by a third-party pricing vendor. Such valuations may be based on trade prices in active markets for identical assets or liabilities (Level 1 inputs) or valuation models using inputs that are observable either directly or indirectly (Level 2 inputs), such as quoted prices for similar assets or liabilities, yield curve, volatility factors, credit spreads, default rates, loss severity, current market and contractual prices for underlying instruments or debt, broker and dealer quotes, as well as other relevant economic measures. The Company performs certain procedures to corroborate the fair value of its holdings, including comparing valuations obtained from its investment service provider with other pricing sources to validate the reasonableness of the valuations. The Company typically invests in highly rated securities, and its investment policy limits the amount of credit exposure to any one issuer. The policy requires investments in fixed income instruments denominated and payable in U.S. dollars only and requires investments to be investment grade, with a primary objective of minimizing the potential risk of principal loss. The Company considers the declines in market value of its short-term investments to be temporary in nature. Fair values were determined for each individual security in the investment portfolio. When evaluating an investment for other-than-temporary impairment, the Company reviews factors such as length of time and extent to which fair value has been below its cost basis, the financial condition of the issuer and any changes thereto, changes in market interest rates and the Company’s intent to sell, or whether it is more likely than not it will be required to sell the investment before recovery of the investment’s cost basis. As of September 30, 2019, the Company does not consider any of its investments to be other-than temporarily impaired. Contractual maturities of short-term investments as of September 30, 2019, are as follows (in thousands) Estimated Fair Value Due within one year $ 21,001 |

Long Term Debt [Abstract] | |
Notes Payable and Line of Credit | No t In December 2015 the Company amended its amended and restated loan and security agreement with Silicon Valley Bank to include a term loan in the amount of $4.0 million. The loan requires 36 monthly installments of interest and principal. The loan matured on December 1, 2018, The interest rate was fixed at 5.0%. In January 2018 the Company entered into a second amended and restated loan and security agreement (the Amended Loan Agreement) with Silicon Valley Bank. The Amended Loan Agreement modified the amended and restated loan and security agreement to, among other things, increase the aggregate principal amount available under the revolving line of credit from $3.0 million to $10.0 million. It also removed a minimum EBITDA requirement previously applicable to the line of credit and former term loan and maintained the liquidity ratio financial covenant such that the Company must maintain a ratio of cash and cash equivalents plus accounts receivable to outstanding debt under the Amended Loan Agreement minus deferred revenue of 1.25 to 1.00. The Amended Loan Agreement also set a borrowing base limit of 80% of the aggregate face amount of all eligible receivables. No balance was owed on the line of credit as of September 30, 2019 and December 31, 2018. The Company will be required to pay interest on borrowings outstanding, if any, under the revolving line of credit at a floating rate per annum equal to 1% above the Wall Street Journal prime rate (5.0% as of September 30, 2019) (or, if unavailable, the Silicon Valley Bank prime rate) on a monthly basis, so long as the Company maintains a liquidity ratio of cash and cash equivalents plus accounts receivable to outstanding debt under the Amended Loan Agreement minus deferred revenue of 1.25 to 1.00. If this liquidity ratio is not met, the Company will be subject to a minimum interest charge of $3,000 per month and borrowings outstanding, if any, under the revolving line of credit will accrue interest at a floating rate per annum equal to 2% above the Wall Street Journal prime rate (5.0% as of September 30, 2019) (or, if unavailable the Silicon Valley Bank prime rate) on a monthly basis. Prior to the amendment in January 2018, the revolving line of credit bore interest rate at the U.S. prime rate plus 1.25%. The revolving line of credit matures on January 31, 2020. Silicon Valley Bank maintains a first security interest over the Company’s assets, excluding intellectual property, for which Silicon Valley Bank has received a negative pledge. The Amended Loan Agreement contains customary affirmative and negative covenants and events of default applicable to the Company and any of its subsidiaries. The Company was in compliance with its financial covenants in the Amended Loan Agreement as of September 30, 2019. |

Treasury Stock | Note 8. Treasury Stock In August 2017, the Company’s Board of Directors (the Board) approved a share repurchase program (the 2017 Program) pursuant to which the Company could purchase up to $7.0 million of shares of its common stock over the twelve-month period following the establishment of the program. The repurchases under the 2017 Program were made from time to time in the open market or in privately negotiated transactions and were funded from the Company’s working capital. Repurchases were made in compliance with Rule 10b-18 of the Securities Exchange Act of 1934, as amended, subject to market conditions, available liquidity, cash flow, applicable legal requirements and other factors. All shares of common stock repurchased under the Company’s 2017 Program were returned to the status of authorized but unissued shares of common stock. On August 7, 2018, the Board approved an extension to the 2017 Program for an additional twelve-month period ending on August 14, 2019. On September 9, 2019, the Board approved a new share repurchase program pursuant to which the Company may purchase up to $7.0 million of shares of its common stock over the following twelve-months. All shares purchased in the three months ended September 30, 2019 were subject to the new share repurchase program. This newly adopted share repurchase program mirrors all aspects and terms of the 2017 Program as described above. During the three and nine months ended September 30, 2019, the Company repurchased 48,000 and 63,000 shares of common stock, respectively, under the share repurchase programs. For the three months ended September 30, 2019, the shares were repurchased at an average price per share of $12.54 per share, for a total cost of $0.6 million. For the nine months ended September 30, 2019, the shares were repurchased at an average price of $12.75 per share, for a total cost of $0.8 million. As of September 30, 2019, the Company repurchased a total of $3.6 million in common stock under the recently expired 2017 Program. |

Income Tax Disclosure [Abstract] | |
Income Taxes | Note 9. Income Taxes The Company’s effective income tax rate was 16.1% and (2.9)% for the nine months ended September 30, 2019 and 2018, respectively. The variance from the U.S. federal statutory tax rate of 21% for each of the nine months ended September 30, 2019 and 2018, was primarily attributable to the utilization of deferred tax attributes that had a full valuation allowance. Management assesses its deferred tax assets quarterly to determine whether all or any portion of the asset is more likely than not unrealizable under Accounting Standards Codification (ASC) Topic 740. The Company is required to establish a valuation allowance for any portion of the asset that management concludes is more likely than not to be unrealizable. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. The Company’s assessment considers all evidence, both positive and negative, including the nature, frequency and severity of any current and cumulative losses, taxable income in carryback years, the scheduled reversal of deferred tax liabilities, tax planning strategies, and projected future taxable income in making this assessment. At September 30, 2019, and December 31, 2018, the Company has a valuation allowance against net deferred tax assets but for the exclusion of a deferred tax liability generated by goodwill (an indefinite lived intangible) that may not be considered a future source of taxable income in evaluating the need for a valuation allowance. |

For fully vested stock options, the aggregate intrinsic value as of September 30, 2019, and December 31, 2018, was $3,043,000 and $2,485,000, respectively. For stock options expected to vest, the aggregate intrinsic value as of September 30, 2019 and December 31, 2018 was $935,000 and $993,000, respectively. At September 30, 2019, and December 31, 2018, there was $4,090,000 and $2,781,000, respectively, of total unrecognized compensation cost related to unvested stock options granted under the Company’s equity plans. That cost is expected to be recognized over the next three years and is based on the date the options were granted. Restricted Stock During the nine months ended September 30, 2019, the Company granted 95,478 Restricted Stock Units (RSUs) at a weighted average grant date fair value of $11.35 per share. No RSUs vested during the three and nine months ended September 30, 2019. As of September 30, 2019, the Company has 96,605 RSUs outstanding at a weighted average grant date fair value of $11.42 per share and a weighted average remaining contractual term of 1.8 years. As of September 30, 2019, there was $919,000 of total unrecognized compensation cost related to unvested RSUs. Employee Stock Purchase Plan (ESPP) The Company maintains the Employee Stock Purchase Plan (ESPP) that provides employees an opportunity to purchase common stock through payroll deductions. The ESPP is implemented through consecutive 6-month offering periods commencing on March 1 and September 1 of each year. The first offering period under the ESPP commenced on March 1, 2019. The purchase price is set at 85% of the fair market value of the Company's common stock on either the first or last trading day of the offering period, whichever is lower, and annual contributions are limited to the lower of 20% of an employee's eligible compensation or such other limits as apply under Section 423 of the Internal Revenue Code for such plans such as the ESPP. The ESPP is intended to qualify as an employee stock purchase plan for purposes of Section 423 of the Internal Revenue Code. Based on the 15% discount and the fair value of the option feature of the ESPP, it is considered compensatory. Compensation expense is calculated using the fair value of the employees’ purchase rights under the Black-Scholes model. The Company currently uses authorized and unissued shares to satisfy share award exercises. The Company received proceeds of $97,000 from the issuance of 10,000 shares under the ESPP in August 2019. |

Accounting Policies [Abstract] | |
Basis of Presentation | Basis of Presentation The accompanying unaudited condensed financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) and applicable rules and regulations of the Securities and Exchange Commission (SEC) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Interim financial results are not necessarily indicative of results anticipated for the full year. As such, the information included in this quarterly report on Form 10-Q should be read in conjunction with the financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2018, from which the balance sheet information herein was derived. The unaudited condensed balance sheet as of December 31, 2018, included herein was derived from the audited financial statements as of that date but does not include all disclosures including notes required by GAAP. The unaudited condensed statements of operations for the three and nine months ended September 30, 2019 and 2018, and the balance sheet data as of September 30, 2019, have been prepared on the same basis as the audited financial statements. In the opinion of management, the accompanying unaudited condensed financial statements reflect all adjustments, consisting of normal and recurring adjustments, necessary for a fair presentation of results of the Company’s operations and financial position for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full year ending December 31, 2019, or for any future period. |
Segment Information | Segment Information The Company’s operations are located primarily in the United States and most of its assets are located in San Diego, California and Scottsdale, Arizona. The Company operates in one segment related to the sale of antenna products. The Company’s chief operating decision-maker is its chief executive officer, who reviews operating results on an aggregate basis and manages the Company’s operations as a single operating segment. |
Use of Estimates | Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include valuation of intangible assets and goodwill. |
Reclassifications | Reclassifications Certain amounts in the prior period financial statements have been reclassified to conform to the presentation of the current period financial statements. |
Fair Value Measurements | Fair Value Measurements The carrying values of the Company’s financial instruments, including cash and cash equivalents, trade accounts receivable, accounts payable, and accrued liabilities approximate their fair values due to the short maturity of these instruments. Fair value measurements are market-based measurements, not entity-specific measurements. Therefore, fair value measurements are determined based on the assumptions that market participants would use in pricing the asset or liability. The Company follows a three-level hierarchy to prioritize the inputs used in the valuation techniques to derive fair values. The basis for fair value measurements for each level within the hierarchy is described below: • Level 1: Quoted prices in active markets for identical assets or liabilities. • Level 2: Quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs are observable in active markets. • Level 3: Valuations derived from valuation techniques in which one or more significant inputs are unobservable in active markets. |
Cash Equivalents and Short Term Investments | Cash Equivalents and Short-Term Investments Cash equivalents are comprised of short-term, highly liquid investments with maturities of 90 days or less at the date of purchase. Short-term investments consist predominantly of commercial paper, corporate debt securities, U.S. Treasury securities and asset backed securities. The Company classifies short-term investments based on the facts and circumstances surrounding the investments at the time of purchase and evaluates such classification as of each balance sheet date. All short-term investments are classified as available-for-sale securities as of September 30, 2019, and are recorded at estimated fair value. Unrealized gains and losses for available-for-sale securities are included in accumulated other comprehensive income (loss), a component of stockholders’ equity. Realized gains and losses are included in other income, in the unaudited condensed statements of operations. The Company evaluates its investments to determine whether those with unrealized loss positions are other than temporarily impaired. Impairments are considered to be other than temporary if they are related to deterioration in credit risk or if it is likely that the Company will sell the securities before recovery of their cost basis. |
Inventory | Inventory The majority of the Company’s products are manufactured by third parties that retain ownership of the inventory until title is transferred to the customer at the shipping point. In certain instances, shipping terms are delivery at place and the Company is responsible for arranging transportation and delivery of goods ready for unloading at the named place. The Company bears all risk involved in bringing the goods to the named place and records the related inventory in transit to the customer as inventory on the accompanying balance sheet. The Company also manufactures certain of its products at its facility located in Scottsdale, Arizona. Inventory is stated at the lower of cost or net realizable value. For items manufactured by the Company, cost is determined using the weighted average cost method. For items manufactured by third parties, cost is determined using the first-in, first-out (FIFO) method. Any adjustments to reduce the cost of inventories to their net realizable value are recognized in earnings in the current period. As of September 30, 2019, the Company’s inventories consist primarily of raw materials. Provisions for excess and obsolete inventories are estimated based on product life cycles, quality issues, and historical experience. As of September 30, 2019, there is no provision for excess and obsolete inventories. |
Accumulated Other Comprehensive Income (Loss) | Accumulated Other Comprehensive Income (Loss) Comprehensive income (loss) is comprised of net income (loss) and other comprehensive income (loss). Accumulated other comprehensive income (loss) on the unaudited condensed balance sheet at September 30, 2019, includes unrealized gains and losses on the Company’s available-for-sale securities. |

An entity will, therefore, perform the goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount, recognizing an impairment charge for the amount by which the carrying amount exceeds the fair value, not to exceed the total amount of goodwill allocated to the reporting unit. An entity still has the option to perform a qualitative assessment to determine if the quantitative impairment test is necessary. ASU 2017-04 will be effective for the Company in annual periods beginning after December 15, 2020, and interim periods within fiscal years beginning after December 15, 2021, with early adoption permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company has not yet determined whether it will early adopt ASU 2017-04 and is evaluating the impact the standard will have on its ongoing financial reporting.
