Design of E-plane monopulse feeder using multimode corrugated rectangular waveguide

A structure for an optimum monopulse feeder is proposed using a multimode corrugated waveguide. The analysis of the proposed structure is performed using the hybrid multimode concept of the corrugated waveguide and the mode matching techniques at the waveguide junction. The design procedure is explained and the experiment is compared with the theoretical results. A good agreement between the theory and measurement is observed.<>
