Abstract

In this contribution, a novel planar orthomode transducer is presented. It is based on a stepped waveguide technique that makes the transducer small and easy to handle. Several electromagnetic simulations were performed in order to optimize the transducer's structure and to investigate possible production tolerances, respectively. The developed orthomode transducer was built up and measured in a back to back assembly. The broadband measurement results as well as its planar structure allow different kind of feeding which make the presented orthomode transducer suitable for numerous applications.
