  • Ortho-mode transducer and diplexer
    Patent number: 10326189
    Abstract: A method includes receiving, through a vertical polarization port of an orthogonal-mode transducer (OMT), a vertical polarized signal from a vertical polarization diplexer, and receiving, through a horizontal polarization port of the OMT, a horizontal polarized signal from a horizontal polarization diplexer. The method also includes receiving, through a common port of the OMT, a circular polarized signal comprising the vertical and horizontal polarized signals. The common waveguide includes a septum polarizer configured to split or combine between the circular polarized signal, and the vertical polarized signal and the horizontal polarized signal.
