Problems solved by technology

[0002] Wireless communication products such as antennas need to perform standing wave detection to obtain the standing wave ratio and evaluate whether the quality of the product meets the requirements through the size of the standing wave ratio. Usually, components such as couplers and detectors are used to indirectly measure the standing wave ratio of the product. However, , because the accuracy of components such as couplers is difficult to guarantee, the measurement results of standing wave ratio are not accurate enough

Abstract

The invention discloses a standing wave detection method. The standing wave detection method is used to detect the standing wave ratio of the antenna (12) of the antenna assembly (10), and the standing wave detection method includes: (S1) obtaining the measured reflection coefficient of the antenna (12); (S2) obtaining calibration parameters; (S3 ) calculating an actual reflection coefficient of the antenna (12) based on the measured reflection coefficient and the calibration parameters; and (S4) calculating a standing wave ratio of the antenna (12) based on the actual reflection coefficient. The invention also discloses a standing wave detection device (20) and an electron gun (100). After the above-mentioned standing wave detection method, standing wave detection device (20) and electron gun (100) obtain the measured reflection coefficient of the antenna (12), they also calculate the actual reflection coefficient through calibration parameters for the measured reflection coefficient, and further pass the actual reflection coefficient The standing wave ratio of the antenna (12) is calculated, and the accuracy of the standing wave ratio of the antenna (12) thus obtained is relatively high.
