Problems solved by technology

[0005] In a multi-probe non-reflection anechoic chamber, the measurement antenna is usually set on a ring-shaped support structure. In a conventional SISO/MIMO anechoic chamber, in order to meet both multi-probe SISO testing and MIMO testing, the number of antennas required will be large. In order to To ensure the test accuracy, it is necessary to ensure a certain distance between the antennas to control the coupling interference between the antennas to a certain extent (for example -30dB). Usually, one or more antenna support rings

Example Embodiment

[0025] The embodiments of the present invention will be described in detail below. It should be emphasized that the following description is only exemplary, and is not intended to limit the scope of the present invention and its application.

[0026] Refer to Figure 1 to Figure 4 In one embodiment, a wireless device testing system includes a shielding shell 600 forming a dark room, a test antenna 300 installed on the inner wall of the shielding shell 600, and a test turntable 400 located at the center of the shielding shell 600 . The test turntable 400 is used to place a wireless device to be tested, such as a wireless terminal such as a mobile phone. The test antenna 300 includes 8 multiplexed dual-polarized probe antennas 301-308 arranged in a circular ring around the inner wall of the shielding shell 600 at 45° intervals, and 8 multiplexed dual-polarized probe antennas 301-308. Arrange along the same ring (the ring in this embodiment refers to a virtual ring that uses the i...

Abstract

The invention discloses a wireless equipment test system which comprises eight multiplex bipolar probe antennas which are spaced at 45 degrees and annularly arrayed around the inner wall of a shielding shell and three SISO test bipolar probe antennas arrayed along the same ring, wherein the distribution mode of the SISO test bipolar probe antennas enables these bipolar probe antennas to form eleven antenna sequences distributed on one ring at logic intervals of 15 degrees; therefore, multiplexing of part of the antennas is realized in the test system, namely a certain quantity of antennas are used for both SISO test and MIMO test; compared with a conventional test system, a small quantity of antennas can be used to perform various tests; antenna supporting rings are not necessary to additionally arrange; meanwhile, a dark room of a smaller size can be adopted to realize high measurement precision.

Description

technical field [0001] The invention relates to the communication field, in particular to a wireless device testing system. Background technique [0002] Wireless communication technology is a technology that uses the characteristics of electromagnetic waves that can propagate in free space, and transmits and exchanges information between two or more points through the air (non-wired). Therefore, as the core component of transmitting and receiving wireless communication information carrier—electromagnetic waves, the performance of the antenna directly determines the ability of the wireless terminal to realize communication. [0003] The traditional communication system uses a single transmitting antenna and a single receiving antenna, which is called SISO (Single-InputSingle-Output) system, while the MIMO (Multiple-InputMultiple-Output) system includes multiple transmitting antennas and multiple receiving antennas, which can fully Using space resources, multiple antennas ca...
