[0002] With the development of electronic warfare, the frequency of material use has expanded to the P band at the low frequency end and to the Ku band at the high frequency end, and electromagnetic characteristic parameter performance testing within a wider frequency band is required. Due to the limitation of antenna frequency bandwidth, two or more antennas are often required for broadband testing.

[0003] In traditional technology, for the reflectivity test of electromagnetic characteristic parameters, the conventional antenna installation method is to fix the antenna directly to the crossbar of the reflectivity test equipment. When it is necessary to replace the antenna of a different frequency or change the polarization direction of the antenna, the antenna can only be manually disassembled and assembled. Manual disassembly and assembly of the antenna cannot ensure that the position of the antenna relative to the crossbar does not change, which affects the test accuracy and is time-consuming and labor-intensive.
