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.

The disclosure provides an ultra-wideband non-metal horn antenna, which includes three combinable non-metal elements such as an impedance matching member, a field adjustment member and an outer cover member. The impedance matching member and the field adjustment member are respectively disposed with a first and second groove structures. The field adjustment member is connected between the impedance matching member and the outer cover member. Therefore, the horn antenna of the disclosure can have a more symmetrical radiation pattern, a smaller antenna size, and ultra-wideband performance.

An optical and electrical hybrid beamforming transmitter, receiver, and signal processing method are provided. The transmitter includes, but is not limited to, two photoelectric converters, two adjusting circuits, and an antenna array. The photoelectric converter converts an optical signal into an initial electric signal, respectively. The adjusting circuit is coupled to the photoelectric converter, and are adapted for delaying the initial electric signal according to an expected beam pattern formed by the antenna array, respectively, to output an adjusted electric signal. The antenna array includes two antennas that are coupled to the adjusting circuit. The antenna radiates electromagnetic wave according to the adjusted electric signal. Accordingly, a phase of the signal may be adjusted, and the number of the elements may be reduced.

A transition structure for millimeter wave is provided. The transition structure includes a first layer signal element coupled to an end of a first transmission line and a plurality of first layer ground elements surrounding the end of the first transmission line equidistantly from the end of the first transmission line and disposed along two opposite sides of a strip body of the first transmission line equidistantly from the strip body of the first transmission line. The transition structure further includes an intermediate layer signal element coupled to the first layer signal element and a plurality of intermediate layer ground elements surrounding the intermediate layer signal element quasi-coaxially. A multilayer transition structure including a multilayer structure and the transition structure is also provided. Therefore, the problem of operating frequency caused by the thickness of the multilayer structure can be overcome, thereby increasing the resonance frequency of the multilayer structure.
