Radiation, Scattering, and Guidance of Electromagnetic Fields by Arbitrarily Shaped Structures Embedded in Layered Dielectric Media

Abstract

We have undertaken a study of a waveguide-excited microstrip patch antenna. Unlike some previous treatments of this problem, the technique we have developed allows for an arbitrarily shaped patch and/or for an arbitrarily shaped aperture. We use the image theory to cast the excitation problem as a periodic one, which allows the structure below and above the ground plane to be treated in a uniform fashion. We have also begun a study of three-dimensional microstrip discontinuities, like vias connecting two microstrip lines or air bridges connecting the outer conductors of a coplanar waveguide.
