Title:
WAVEGUIDE ANTENNA ASSEMBLY, RADAR, TERMINAL, AND PREPARATION METHOD FOR WAVEGUIDE ANTENNA ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2023/185843
Kind Code:
A9
Abstract:
The present application relates to the technical field of communication and aims to solve the problem of a poor matching degree between a waveguide antenna and a transition structure. Provided are a waveguide antenna assembly, a radar, a terminal, and a preparation method for the waveguide antenna assembly. The waveguide antenna assembly comprises a first base plate, a second base plate and a transition structure. The first base plate is provided with a first plate surface and a second plate surface facing away from the first plate surface. The transition structure is arranged on the first base plate, a microstrip connecting end of the transition structure is arranged on the first plate surface, and a waveguide connecting end is arranged on the second plate surface. The second base plate is arranged on the second plate surface and is provided with a through hole, the through hole penetrates through the thickness of the second base plate, and a conductive layer is provided on an inner wall of the through hole. The through hole, which has the conductive layer, can form a waveguide antenna, and the projection of the waveguide connecting end on the second base plate is located in the through hole, so that the through hole is coupled to the transition structure. The waveguide antenna assembly provided by the present application can ensure good matching and signal transmission performance between the transition structure and the waveguide antenna.
