Problems solved by technology

[0003] When testing the antennas of wireless terminals, each antenna is tested in the whole machine state. Since multiple antennas on the wireless terminal are distributed in different positions, it is difficult to accurately test the accuracy of each antenna during the whole machine test. Power, so there will be a problem of false detection, and the wireless terminal with normal performance will be falsely detected as a bad product, thereby reducing the generation efficiency

Abstract

The present invention provides an antenna testing apparatus (200), system and method, and a related device. The antenna testing apparatus (200) comprises a shielding box (100), and a terminal to be tested (101) and an antenna array (103) disposed in the shielding box (100). The antenna array (103) comprises a plurality of test antennae (104) satisfying pre-set conditions, the pre-set conditions referring to non-interference between any two adjacent test antennae (104). A multi-path switch (106) is connected to each test antenna (104). The multi-path switch (106) can conduct a path between a tester (300) and a target test antenna of which target power is greater than or equal to a pre-set value under the control of an information processing apparatus (400), such that the tester (300) only tests a target antenna on the terminal to be tested (101) by means of the target test antenna of which the target power is greater than or equal to the pre-set value. An insertion loss in a test process is low, thereby automatically selecting a target test antenna without manual operations, and improving antenna power test accuracy as well as test efficiency.

Description

technical field [0001] The present invention relates to the field of information processing devices, in particular to an antenna testing device, system, method and related equipment. Background technique [0002] With the enrichment of wireless applications, more and more antennas are integrated into a wireless terminal. For example, wireless terminals such as mobile phones, tablet computers, and multi-function players may be integrated with global positioning system GPS, wireless fidelity Wi-Fi, global mobile communication system GSM, code division multiple access CDMA, universal mobile communication system UMTS, Various communication systems such as near field communication (NFC) and their corresponding multiple antennas. [0003] When testing the antennas of wireless terminals, each antenna is tested in the whole machine state. Since multiple antennas on the wireless terminal are distributed in different positions, it is difficult to accurately test the accuracy of each ...
