  • Patent number: 11205827
    Abstract: Provided is a rapid over-the-air (OTA) production line test platform, including a device under test (DUT), an antenna array and two reflecting plates. The DUT has a beamforming function. The antenna array is arranged opposite to the DUT, and emits beams with beamforming. Two reflecting plates are disposed opposite to each other, and are arranged between the DUT and the antenna array. The beam OTA test of the DUT is carried out by propagation of the beams between the antenna array, the DUT and the two reflecting plates. Accordingly, the test time can be greatly shortened and the cost of test can be effectively reduced. In addition to the above-mentioned rapid OTA production line test platform, platforms for performing the OTA production line test by using horn antenna arrays together with bending waveguides and using a 3D elliptic curve are also provided.
