Patent ID: 8816930

Claim:
A waveguide orthomode transducer, comprising: a junction having a main waveguide and four auxiliary waveguides lying along the two orthogonal main axis of the junction and defining four quadrants (I, II, III, IV); a combination network comprising two magic tees, each having an E port, two opposed common-ports, and a H-port; an E-plane tee junction having a Σ-port and two opposed common-ports; and an E-plane tee junction having a Δ-port and two opposed common-ports; wherein: two auxiliary waveguides defining a first quadrant (I) are respectively connected to the common-ports of one of the magic tees and the two other secondary waveguides defining a second quadrant (II) opposite to the first quadrant (I) are connected to the common-ports of the other magic tee; and in that tee junctions are used to connect similar magic tee ports (E-port, H-port); so that the transducer separates towards two different outputs two orthogonally polarized signals entering at said main waveguide and reciprocally two signals entering respectively in the Σ-port and the Δ-port of the tees junctions are combined with orthogonal polarizations in said main waveguide.
