Abstract

An embodiment of the present invention provides a multi-polarization substrate integrated waveguide antenna. The multi-polarization substrate integrated waveguide antenna of the present invention has a multi-layer structure, which includes in order from top to bottom: a first metal copper clad layer, a first dielectric layer, a second metal copper clad layer, a second dielectric layer and a third A metal clad copper layer, wherein metallized through holes are provided on the first dielectric layer and the second dielectric layer, and metallized through holes are provided on the first metal clad copper layer and the second metal clad copper layer etch slot. The embodiment of the present invention solves the problem that feeding efficiency decreases when microstrip line feeding is used in high-frequency applications.

Description

technical field [0001] The embodiment of the present invention relates to communication technology, in particular to a multi-polarization substrate integrated waveguide antenna. Background technique [0002] In various wireless communication and radar systems, the transmission and reception of information depends on the antenna. With the rapid development of large-capacity, multi-functional, ultra-broadband integrated information systems, the amount of information carried on the same platform has greatly increased, and the number of antennas required has also increased accordingly. This is in contradiction with the development trend that requires the antenna to reduce the overall cost of the integrated information system, reduce the weight, reduce the radar cross section of the platform, and achieve good electromagnetic compatibility characteristics. The emergence of multi-polarized antennas can effectively solve this contradiction. It can dynamically change its working pol...
