Abstract

In this paper, the finite-difference time-domain (FDTD) method is used for the analysis of a line-fed rectangular patch antenna. This is carried out by using the Berenger perfectly matched layer (PML) as well as Mur's first order absorbing boundary conditions (Mur'Sfoc). The time domain field response, the return loss, and the input impedance of the structure are obtained. In addition, the effect of patch width and the feeder displacement are studied. The results obtained by the FDTD with PML are found to be in better agreement with the published measured data than those obtained by the FDTD with Mur's FOC.
