| A generalized algorithm for the analysis of multilayered patch antenna is presented based on the 3D-FDFD (Frequency Domain Finite Difference) method with non-uniform meshes. The Mur’s ABCs of the second order and the ABCs based on the concept of field average are simultaneously applied at the terminating boundary mesh nodes. The compressed storage and least-square method is adopted to solve the system of algebraic linear equations with sparse coefficient matrix, and is proved to be accurate and reliable compared with the reported data. |
