Research output: Chapter in book / Conference proceedingConference article published in proceeding or bookAcademic researchpeer-review


The complex resonant frequencies of a circular microstrip patch mounted on a spherical body are investigated using the spectral domain method. In this method, the effects of the dielectric substrate and of the metallic sphere are incorporated by the rigorous Green's function formulation. Vector Legendre series is defined to simplify the process of formulation. Galerkin's procedure is employed to solve for the complex resonant frequencies. The cavity model surface current functions are used as the basis functions. The resonant frequencies and Q-factors of the TM11 mode are presented.
