A comparison between the multiple-region (MR) and dual-grid (DG) finite-difference time-domain (FDTD) methods for the analysis of antenna arrays is presented. The application of both methods shows that the DG-FDTD method is more accurate when computing the mutual coupling between antennas. Besides, it exhibits multi-surface capabilities that make possible the fast and accurate analysis of antenna arrays, including mutual coupling and edge effects.
