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: Provided is a low-leakage automatic adjustable diplexer including a body, a thin plate and two resonant regulators. The body has therein cuboid waveguide channels each having a feeding portion, a reception port portion, a transmission port portion, a fitting portion, a first filtering portion, a second filtering portion, first E/H conversion units connected to two ends of the first filtering portion, respectively, and second E/H conversion units connected to two ends of the second filtering portion, respectively. The thin plate is clamped inside the body. The resonant regulators each have a plurality of frequency disturbance elements adjustably protruding into the first and second filtering portions.
