Title:
MULTIPLE-ANTENNA WIRELESS DEVICE RADIO INTERFACE TESTING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/220878
Kind Code:
A1
Abstract:
Disclosed in the present invention is a multiple-antenna wireless device radio interface testing apparatus, comprising: a darkroom, a wave-absorbing material being disposed on an inner wall of the darkroom; multiple coupling probes, the multiple coupling probes being movably disposed in the darkroom and used to simultaneously or individually perform power coupling transmission for an antenna within a pre-determined near-field radiation range of a location of a current probe, a maximum dimension of metal in all cross-sections of probe ends of coupling probes within five centimeters of a feed line being less than or equal to five centimeters, so as to acquire transceiving performance of the multiple-antenna wireless device. According to the testing apparatus of embodiments of the present invention, it is possible to use an individual near-field coupling means for an antenna, and it is also possible to simultaneously or individually perform radio interface testing for an antenna within a near-field radiation distance, which not only increases testing operation efficiency, but also effectively increases testing accuracy.
