Abstract
Embodiments of the present invention provide a multi-polarization substrate integrated waveguide antenna. In the multi-polarization substrate integrated waveguide antenna of the present invention, the antenna is of a multi-layer structure and includes a first metal copper clad layer, a first dielectric layer, a second metal copper, clad layer, a second dielectric layer, and a third metal copper clad layer successively from top to bottom, where plated through holes are provided on both the first dielectric layer and the second dielectric layer, and etching grooves are provided on both the first metal copper clad layer and the second metal copper clad layer. The embodiments of the present invention resolve a problem that feeding efficiency is reduced in a high frequency application when a microstrip is used to feed electricity.
