Abstract

A rigorous analysis of the resonance frequency problem of both the cylindrical-rectangular and the wraparound microstrip structure is presented. The problem is formulated in terms of a set of vector integral equations. Using Galerkin´s method to solve the integral equations, the complex resonance frequencies are studied with sinusoidal basis functions which incorporate the edge singularity. The complex resonance frequencies are computed using a perturbation approach. Modes suitable for resonator or antenna applications are investigated. The edge singularity of the patch current is shown to have no significant effect on the accuracy of the results. It is shown that the HE₁₀ modes of the cylindrical-rectangular and wraparound patches are more appropriate for resonator applications. The HE₀₁ and TE ₀₁ modes of the cylindrical-rectangular and wraparound patches, respectively, are efficient radiating modes
