Design and measurement of metallic post-wall waveguide components

Abstract

In this paper we discuss the design and measurement of a set of metallic post-wall waveguide components for antenna feed structures. The components are manufactured on a single layer printed circuit board and excited by a grounded coplanar waveguide. For a straight transmission line, a 90 • H-plane bend, and a H-plane T-junction, we compare measurements with simulations obtained from commercial software. In a next phase, the set of test components will be used to validate a software tool for component analysis. This tool is based on our own numerical method and will be integrated with a circuit simulator.
