Abstract

The invention discloses a slot array PCB antenna. The slot array PCB antenna comprises a first reflector and a second reflector which are designed integrally; a first radiating element layer and a first director are sequentially arranged above the first reflector, and a second radiating element layer and a second director are sequentially arranged above the second reflector; the connection portion between the first reflector and the second reflector is connected with a stub frequency selective network through a transmission line transformer, and the first radiating element layer and the second radiating element layer are respectively provided with a first feeder access point and a second feeder access point which are connected through a coaxial transmission line, the reflectors, the radiating element layers and the directors are all of a double-sided copper clad PCB structure, and a metalized through hole array is distributed in the double-sided copper clad board. The slot array PCB antenna has the advantages of good directivity and high gain of a yagi antenna as well as small size, light weight, low cost, high performance, integration and installation easiness and the like of a common planar antenna.

Description

technical field [0001] The invention relates to a radio technology, in particular to a slot array PCB antenna. Background technique [0002] In radio technology equipment that transmits information by electromagnetic waves, such as radio, television, communications, navigation, radar, etc., PCB antennas are an essential and important part. In high-efficiency satellites, aircraft and mobile communication mobile phone applications, PCB antennas are higher favor. However, current PCB antennas usually have low gain, low directivity, large size, heavy weight, and difficulty in integration. Contents of the invention [0003] The object of the present invention is to provide a PCB antenna with higher gain, good directivity, small size, light weight and easy integration. [0004] Technical scheme of the present invention is: [0005] The advantages of the present invention are: [0006] A slot array PCB antenna, comprising an integrated first reflector and a second ...
