Abstract

A cross-shaped dielectric resonator antenna, designed for circular polarization, is analyzed via the conformal finite difference time domain (CFDTD) technique. The conformal technique, which can handle canted surfaces that do not conform to the Cartesian system of co-ordinates, can be used to generate accurate results with a relatively coarse mesh. For instance, is shown that the conformal FDTD offers a 2:1 advantage over staircasing, without compromising the level of accuracy.
