Bandwidth enhancement of dielectric resonator antennas
An experimental investigation of bandwidth enhancement of dielectric resonator antennas (DRAs) using parasitic elements is reported. Substantial bandwidth enhancement for the HE/sub 11/spl delta// mode of the stacked geometry and for the HE/sub 13/spl delta// mode of the coplanar collinear geometry has been demonstrated. Excellent radiation patterns for the HE/sub 11/spl delta// mode were also recorded. Because of excellent return loss and radiation characteristics, the DRA should be excited in HE/sub 11/ mode when used as radiating elements in an array.<>
