On the comparison between multiple-region and dual-grid finite-difference time-domain methods for the analysis of antenna arrays

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, i...

Description
Summary: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. © 2010 Wiley Periodicals, Inc.
