Compact Orthomode Transducer with Broadband Beamforming Capability

Juan Ramon Mosig, Anja Skrivervik, Emile Jacques de Rijk

A compact and broadband orthomode transducer (OMT) with two dual linearly polarized ports is reported here for the first time. The component is based on a combination of two ridged Boifot junctions through a series of power dividers that act as an embedded ...
