Description

【Technical field】 [0001] The present application relates to the technical field of testing, in particular to an antenna testing system. 【Background technique】 [0002] With the advancement of technology, electronic devices such as mobile phones have been widely popularized. Electronic devices often include antennas to communicate with other electronic devices. Before the electronic device leaves the factory, or when the electronic device is being repaired, the performance of the antenna in the electronic device is often tested to determine whether the antenna is qualified. In the traditional technology, more test instruments are usually used when testing the antenna in the electronic device. [0003] Antenna test system is a set of automatic test system for antenna radiation field scanning, data collection, test data processing and test result display and output under the control of central computer. The whole antenna far-field test system consists of two parts: hardware ...
