A matched E-H plane T-junction for X-band applications

Abstract

This paper presents a method of moment-based analysis of an E-H plane T-junction to find its scatteringparameters. The results show that the network is not matched at its ports. Therefore, matching networks have beenincluded in the structure to establish matching at the ports. The matching structure includes an inductive window atthe H-plane arm and a bisected funnel structure at the junction. Results of the modified structure show simultaneousmatching at all the four ports at 9 GHz, which makes it suitable for X-band application.
