Abstract :
The problem of a rectangular microstrip patch antenna on arbitrary anisotropic dielectric substrate is treated. The finite-difference time-domain (FDTD) method with perfectly matched layer absorber (PML) is applied to determine the time domain field response, the return loss, the input impedance and the radiation pattern of the proposed structure. In addition, the effect of feeder displacement is studied. The results obtained by the FDTD with PML are found to be in good agreement with the published data
