A new type of the matching structure of a H-plane T-junction for a high power system

This paper presents a H-plane T-junction which is designed for the feed networks of waveguide antenna array. The purpose of the T-junction is to divide power and phase equally without any reflection. To do so, we usually add an iris or a post in the junction area so that this iris or post behaves as an inductor and makes each port of the tee-junction matched [1]-[4]. By changing its shape and the location, it can divide power equally without reflection.
