Abstract

A hybridization of the finite element method (FEM) and the spectral domain method of moments (MoM) is utilized in the analysis of cavity-backed patch antennas mounted on an infinite ground plane. The spectral domain MoM models the fields in the external region of the cavity through the use of the half-space Green's function whereas the FEM models the fields inside the cavity using linear edge-based tetrahedral elements. The two regions are coupled through the continuity of the fields in the aperture. Results of analysis are presented.
