Abstract
An orthomode coupler ( ) for directing both satellite uplink and downlink signals. The coupler ( ) includes a waveguide structure ( ) having a first cylindrical section ( ), a conical section ( ) and a second cylindrical section ( ) providing a waveguide chamber ( ) therein. The conical section ( ) provides impedance matching of the downlink signal between the waveguide structure ( ) and a plurality of symmetrically disposed downlink waveguides ( ). The waveguides ( ) are positioned around the waveguide structure ( ) and are in signal communication with the waveguide chamber ( ) through openings in the tapered section ( ). Irises ( ) are provided at the connection between the downlink waveguides ( ) and the waveguide chamber ( ) for impedance matching purposes.
