A domain-decomposition/reciprocity technique for the analysis of arbitrarily-shaped dielectric-loaded microstrip antennas mounted on circularly-cylindrical platforms

Werner, Mouyis and Mitra (see IP Annual Review of Progress in Applied Computational Electromagnetics, vol.1, p.508-515, 1999) introduced an approach for calculating the far-field radiation patterns for microstrip patch antennas mounted on dielectric-coated circular cylinders using the reciprocity technique. This paper presents an extension for this procedure to include the effects of a superstrate in the far-field radiation patterns of these antennas. The superstrate analysis procedure is shown to be both accurate and efficient, possessing the same advantages as the substrate-only analysis. The example of an elliptical microstrip patch antenna mounted on a dielectric-coated circularly-cylindrical platform with a superstrate covering is presented to demonstrate the accuracy and usefulness of this technique.
