ABSTRACT:
There is disclosed an ortho-mode transducer. An annular common waveguide may be defined by an outside surface of an inner conductor and an inside surface of an outer conductor, the outside surface and the inside surface concentric about a waveguide axis. A first port may couple a first TE11mode to the annular common waveguide. A second port may couple a second TE11mode to the annular common waveguide, the second TE11mode orthogonal to the first TE11mode. A first back-short may be disposed adjacent to the first port. A second back-short may be disposed on the outside surface of the inner conductor between the first port and the second port.
