The divergence of e-plane T-junction is presented. Its advantages with respect to permitting simultaneous transmission known known as waveguide diplexer design which allows full e-plane height operation, thus permitting good power handling capability, is simple to model, and provides additional tuning parameters for the computer-aided design. The performance of the junction is compared to those of other junctions and its advantages are demonstrated in a full diplexer design. The combined mode-matching and coupled-integral equations code used for the design is verified by measurements and comparison with results obtained by commercially available software packages.
