Abstract

Post wall waveguide is 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. In this study, loss of bending part with the angle of 120° in post wall waveguide was evaluated both numerically and experimentally for microwave. We proposed the best configuration for bending part of the post wall waveguide.
