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 andor 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.
