Calculation of Resonance in Planar and Cylindrical Microstrip Structures Using a Hybrid Technique
A hybrid technique was employed for the analysis of the resonance frequency of thin planar and cylindrical microstrip structures with the patches of arbitrary geometry. The proposed technique utilizes a combination of Galerkin’s moment method and a finite-element method (FEM). In this approach, an FEM is adopted to calculate the patch surface current densities, and a method of moments is utilized to calculate the resonance frequencies of the microstrip structure. The technique allows the analysis of different shaped patches. To verify the validity of the approach, the results were compared with those obtained from commercial software and actual measurements of manufactured prototypes.
