Abstract

A new electromagnetic modeling activity has been carried out resulting in a significant improvement in the design and optimization capability of a feed system consisting of horn connected to an ortho-mode-transducer (OMT). The tools for the analysis of the horn, the OMT, and their combination, resulting in an integral analysis of the feed system, are described. The adopted approach is suitable for the extension of the analysis to waveguide structures, like matching networks, typical of a feed system. Some of the analytical results are supported by experimental results. The recent development of two methods for analysis of the OMT is emphasized.<>
