Abstract
An ortho-mode transducer is disclosed having a common waveguide and two orthogonal port waveguides, each of which is also orthogonal to the common waveguide. Each port waveguide is coupled to the common waveguide with a coupling aperture which will pass signals having a particular polarity and cut off orthogonally polarized signals. The common waveguide is terminated in a shorting plane about one-quarter of the excepted signal wavelength from the vertical midpoint of the port waveguides. The short directs energy from the common waveguide into the port waveguides and directs energy from the port waveguides into the common waveguide.
