[0002] When testing an antenna, in order to avoid the influence of external signals on the test and the interference of the test signal on the external environment, the test is generally carried out in a microwave darkroom (an open outdoor field can also be selected). For the test of antenna radiation characteristics (directional pattern, bandwidth, side lobe and other indicators), it is necessary to use a carrier device to achieve the controllable and precise position of the antenna in space, thereby providing specific spatial position information for the antenna test.

[0003] However, the existing carrier device only has one clamping seat for clamping the component to be tested, which can only be applied to the antenna test of one component to be tested. Different components to be tested have different sizes (such as laptops and mobile phones), and different clamping seats are required to fix them. Therefore, when testing the antennas of different components to be tested, the entire carrier device needs to be disassembled and replaced, and the antenna performance test equipment needs to be adjusted every time the carrier device is replaced, which not only causes wear and tear on the antenna performance test instrument, but also is cumbersome to operate, consumes test time, and has low test efficiency.
