High-directivity radar metal waveguide antenna

Abstract

The utility model provides a high-directivity radar metal waveguide antenna. The high-directivity radar metal waveguide antenna comprises a first main body and a second main body, the first main body is provided with a receiving channel and two first transmission channels, the receiving channel receives a signal source, and a dividing piece between the two first transmission channels divides the signal source into two first radiation signal sources and transmits the two first radiation signal sources through the first transmission channels; the second main body is arranged on one side of the first main body and provided with two second main transmission channels and two second auxiliary transmission channels arranged on the two sides of the two second main transmission channels, the second main transmission channels are provided with main receiving holes, and coupling holes are formed between the second auxiliary transmission channels and the second main transmission channels in a penetrating mode. The first radiation signal source is divided into two second radiation signal sources through coupling of the coupling hole, and the two second radiation signal sources are radiated and output through the second main transmission channel and the second auxiliary transmission channel.
