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

A new efficient technique for the analysis of corrugated surface wave antennas with infinite ground plane fed by a parallel-plate waveguide is presented, termed the hybrid method of moments/uniform geometrical theory of diffraction (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 previous approximate solution
