Abstract
An ortho-mode transducer has a common port having a longitudinal axis, a single-polarized back port having a longitudinal axis, a transition element connecting the common port and the single-polarized back port, the longitudinal axis of the single-polarized back port being substantially aligned with the longitudinal axis of the common port; a single-polarized side port, and a hybrid tee waveguide junction connecting the single-polarized side port to the transition element. The hybrid tee waveguide junction includes a balanced pair of side arm waveguides connecting the single-polarized side port to the transition element. The ortho-mode transducer prevents the generation of higher order modes, and ensures high isolation in a compact three-dimensional profile.
