Resonance microstrip structure with patch of arbitrary convex geometry with the use of field matching technique

Abstract

An analysis of the resonance frequency problem of planar microstrip structure with patch of arbitrary convex geometry is presented. A full-wave analysis is employed utilizing a combination of Galerkin’s moment method and field matching technique. In this approach, a field matching technique is adopted to calculate the patch surface current densities, and next the method of moments is utilized to calculate resonance frequencies of the microstrip structure. Different convex shapes of patches are considered to verify the validity of the approach. The results agree with those obtained from commercial software and presented in literature.
