  • System for receiving microwave signals having orthogonal polarizations
    Patent number: 4516089
    Abstract: A system is disclosed for coupling orthogonal polarized microwave signals from a reflector to signal processing circuits. The system includes successively a horn, a bandpass filter, a polarizer, a mode separator, and a housing for containing the circuits. The system is constructed from two half-shells.
