ABSTRACT:
A waveguide orthomode transducer. In a first layer a turnstile junction having a main waveguide and four waveguide ports, and four hybrid tees each have an e-port, two opposed side-ports, and an h-port. The hybrid tees are ring-arranged around the turnstile junction so the waveguide ports each communicate with one h-port, so adjacent hybrid tees inter communicate with their respective side-ports, and so the e-ports form two sets of opposed e-ports. In a second layer two h-plane power dividers/combiners each have an axial-port and two opposed side-ports. The h-plane power dividers/combiners are arranged so their respective side-ports communicate with different ones of the two sets of opposed e-ports and so their axial-ports are polarization ports. This permits a single signal with two fundamental orthogonally polarized modes to enter the main waveguide and exit separated at the polarization ports vice versa.
