Abstract
A waveguide includes a waveguide body, a twist plate, and a first and second probes. The waveguide body defines a waveguide cavity therein wherein the waveguide cavity has an aperture at a first end thereof, and wherein the waveguide cavity has a waveguide axis therethrough extending from the first end to a second end. The twist plate is in the waveguide cavity at the second end of the waveguide cavity wherein the twist plate is parallel to the waveguide axis, wherein the twist plate includes a leading edge facing the aperture, and wherein the leading edge includes first and second portions with the second portion being more distant from the aperture than the first portion. The first probe is in the waveguide cavity between the aperture and the leading edge of the twist plate for receiving a first signal having a first polarization entering the aperture. The second probe is in the waveguide cavity between the first probe and the leading edge of the twist plate for receiving a second signal having a second polarization entering the aperture. Related receivers and methods are also discussed.
