Ortho-mode transducer with opposing branch waveguides

摘要

There is disclosed an ortho-mode transducer fabricated as a single piece. The ortho-mode transducer may include a first surface having an aperture defining a common port, a second surface having an aperture defining a vertical port, and a third surface having an aperture defining a horizontal port. The second and third surfaces may be essentially parallel and normal to the first surface. A common waveguide may coupled to the common port, the common waveguide supporting orthogonal vertical and horizontal modes. A vertical branching waveguide may couple the vertical mode between the vertical port and the common waveguide while rejecting the horizontal mode. A horizontal branching waveguide may couple the horizontal mode between the horizontal port and the common waveguide while rejecting the vertical mode.
