Description

technical field [0001] The invention relates to WIFI antenna testing technology, in particular to a WIFI antenna testing system and method. Background technique [0002] At present, wireless fidelity (WIFI) technology is more and more widely used in terminal products such as mobile phones, so a WIFI antenna is generally installed in a terminal product. [0003] In order to ensure the radio frequency performance of the WIFI antenna, in the research and development stage, the radio frequency passive performance of the WIFI antenna must be tested multiple times. Mass production of WIFI antennas cannot be carried out until the relevant standard requirements are met. [0004] In mass production, it is necessary to use instruments such as vector network analyzers to measure the radio frequency passivity of WIFI antennas, that is, return loss. Return loss is a parameter indicating signal reflection performance, indicating that part of the incident power is reflected back to the si...

AI Technical Summary

Problems solved by technology

To measure the quality of a WIFI antenna, it is necessary to measure a sufficient number of frequency points within the working frequency range of the WIFI antenna in order to obtain the return loss of each frequency point. When using a vector network analyzer for testing, it is necessary to manually judge the frequency of each WIFI antenna. The selection of test frequency points is very inefficient, and can only display test charts and data, and cannot directly save test data and analysis results
