Abstract

Post wall wave guide and photonic crystal wave guide are important structure for microwave transmission of integrated circuits with multi-layered substrates. It has simple periodic array of metallic or dielectric cylinders between parallel conducting plates for two-dimensional structure. In this study, return loss from branching part in Y-shaped wave guide was evaluated both numerically and experimentally for microwave. We successfully proposed an improvement method by shifting a post location at the branching part to reduce the return loss.
