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.

Abstract: The present invention discloses a new single polarized array waveguide antenna adapted to be configured above a signal processing substrate, and including an antenna array substrate and a waveguide body. The antenna array substrate includes a plurality of antenna units, each of which having a coupling portion and an impedance matching portion. The waveguide body is configured above the antenna array substrate, and includes a plurality of waveguide channels passing through the waveguide body. Each waveguide channel has a first ridge and a second ridge projecting from wall surfaces and arranged opposite to each other. The first ridge has a first lower withdrawn edge on a lower section of the waveguide channel, and the second ridge has a second lower withdrawn edge on the lower section of the waveguide channel.
