Abstract
The present invention discloses a new dual polarized array waveguide antenna configured above a signal processing substrate and sequentially including an antenna array substrate, a coupling substrate and a waveguide body. The antenna array substrate includes a plurality of patches, each of which having a first coupling portion and a second coupling portion coupled to the signal processing substrate. The top surface of the coupling substrate includes a plurality of coupling pads corresponding to the patches, and each coupling pad is configured above an intersection area of the first coupling portion and the second coupling portion. The waveguide body includes a plurality of waveguide channels passing through the waveguide body and corresponding to the coupling pads. Each waveguide channel has a first ridge pair and a second ridge pair projecting from wall surfaces. Each of the first ridge pair and the second ridge pair has a tapered opening portion withdrawn toward the wall surface of the waveguide channel on an upper section of the waveguide channel. Accordingly, signal transmission quality is improved by the structural arrangement above.
