A numerical code has been developed for the full‐wave determination of the resonant frequencies and quality factors of microstrip patches with right‐angle corners of arbitrary shape. The code is based on the solution of an electric‐field integral equation (EFIE) by means of Galerkin's method in the spectral domain. The numerical code is used for the comparative analysis of microstrip patches of different shapes used as reduced‐size resonators and antennas. Out of the patches studied, the bilateral comb‐shaped patch and the meander‐shaped patch turn out to provide the largest size reduction for a given resonant frequency at the expense of showing at once the largest quality factors. © 2001 John Wiley & Sons, Inc.
