Abstract

Abstract: Finite-difference time-domain (FDTD) method is used to investigate the characteristics of Cylindrical Dielectric Resonator Antenna (CDRA) over a soft ground plane. The effect of the soft ground plane on the input impedance, the radiation pattern, the circular polarization and the mutual coupling between two CDRAs are investigated. Compared with the smooth perfect ground plane, it’s found that the soft ground plane introduces a reduction in the backward radiation, an increase in the circular polarization beamwidth and a reduction in the mutual coupling between the two elements
