Abstract
In this paper, we propose a numerical procedure based on FDTD (Finite Difference Time Domain) method with PML (Perfectly Matched Layer) where we model an antenna as a highly conducting region in three dimensional domain. We apply the procedure to several antennas to verify its effectiveness. In the PML region, we apply a new discretization scheme proposed by the present authors in one dimensional case. The electric current in the antenna is computed afterwards from the surrounding magnetic field. The numerical results show a good performance of our method.
