✦ Synopsis

A hybrid technique that combines the method of moments (MOM) with the finite-element method (FEM) is presented in this article for the analysis of cavity-backed patch antennas embedded in a conducting body. The technique utilizes the MOM approach in the domain exterior to the cavities, and a scattered-field version of the FEM formulation in the interior domains, which may contain material inhomogeneities. Fine features in the interior domains, such as thin-wire structures or coaxial cable feeds, are also analyzed with the MOM / FEM hybridization.
