Analysis of corrugated surface wave antenna using hybrid MOM/UTD technique

A new efficient technique for the analysis of corrugated surface wave anten nas with infinite ground plane fed by a parallel-plate waveguide is present ed, termed the hybrid method of moments/ uniform geometrical theory of diff raction (MOM/UTD) technique. The relative power pattern obtained using the method is compared with the patterns obtained from the previous approximate solution and experiment. The power pattern of the presented method agrees more closely with that of the experiment, compared with that of the previou s approximate solution.
