abstract
A space-domain approach based on a mixed-potential integral equation formulation is developed for efficient computation of complex resonant frequencies of laterally open microstrip-patch resonators of arbitrary shape. The effects of the substratewhich may consist of any number of planar, possibly uniaxially anisotropic, dielectric layersare rigorously incorporated in the formulation by means of the vector and scalar potential Greens functions. The current distribution on the conducting patch is approximated in terms of vector basis functions defined over triangular elements. Computed resonant frequencies, quality factors, modal currents, and far-field radiation patterns are presented for several microstrip resonators. For patches of simple, regular shapes, the results are in agreement with published data obtained by specialized techniques, whichunlike the method presented hereare not easily extendable to arbitrary shapes. 1992 IEEE
