Abstract
Cylindrical and rectangular dielectric resonator antennas (DRAs) using HEM/sub 11/spl delta//, TE/sub 11/spl delta//, and TE/sub 01/spl delta// mode were examined to see the radiation pattern, impedance, field distribution and resonant frequency that were achieved when the DRAs were bisected through an image plane by a conducting sheet. The resultant half DRAs are smaller in volume and have a more directional radiation pattern. The elevation angle of maximum radiation was lowered in some cases. Finite-difference time-domain simulation techniques were used.Keywords
