Analysis of SIW-based Antennas with Arbitrary Slot Shapes

Abstract : In this paper, we propose a basis function sets hybridization for the Mode Matching/Moment Method analysis of SIW slot antennas. In particular, Rao-Wilton-Glisson (RWG) basis functions are used to describe the equivalent magnetic current distributions on arbitrarily shaped slots. Meanwhile, the code employs entire-domain sinusoidal functions for thin rectangular slots. Such an approach aims at providing both fast computing and accurate current description for a wide variety of slot geometries. These aspects are crucial for large SIW antenna optimization. A validation by comparison with a commercial software results is presented.
