摘要：
A methodology that combines the domain segmentation technique, the three-dimensional finite-element method (3-D FEM), and a symmetric matrix Lanczos-Pade algorithm, is used for the fast frequency-sweep analysis of cavity-backed microstrip antennas by using a spherical mode expansion on the radiation boundary. Results for a circular patch antenna validate the proposed method.
