  • Compact orthomode transducer with improved cross-polarization isolation
    Patent number: 7847652
    Abstract: An orthomode transducer includes first, second and third waveguide sections. The first waveguide section is coupled to an antenna port and extends to a first port. The first waveguide section is configured to support the propagation of a signal having a first polarization. The second waveguide section is configured to support the propagation of a signal having a second polarization which is substantially orthogonal to the first polarization. The second waveguide section is coupled to the antenna port and extends to a second port. The second waveguide section further includes a plurality of filter elements. The third waveguide section includes a port coupled to the antenna port, and is configured to support the propagation of the signal having the second polarization. The third waveguide section includes at least one filter element, whereby the number of second waveguide section filter elements is greater than the number of the at least one third waveguide section filter elements.
