Problems solved by technology
[0002] With the rapid development of the wireless communication industry, the demand for antennas used in the wireless communication industry is also increasing, such as radios, televisions, mobile phones, electric meters, etc., all need to transmit sound, video or other data through the antenna , the performance of the antenna is a very critical factor affecting the quality of communication. If there is a performance problem with the antenna, it will directly lead to the degradation of the radio frequency performance of the terminal equipment, which will lead to an increase in cost due to rework. Therefore, the detection process of the antenna after the manufacture is completed is very important
[0003] At present, the VSWR of the antenna is checked by the network analyzer to realize the antenna inspection, and before the network analyzer is used, it needs to be calibrated first, mainly open circuit calibration, short circuit calibration and 50 ohm load calibration, the network analyzer only It can be used to calibrate ordinary antennas. For antennas that are specially customized according to the actual product structure, since the customized antenna can only reflect the impedance of 50 ohms when it is installed inside the product, when the customized antenna is measured separately, its impedance has deviated from 50 ohms , therefore, the performance of custom antennas cannot be precisely measured
