Abstract
The present invention relates to a dielectric resonator antenna (DRA) with bending metallic planes. The ground plane of the dielectric resonator antenna is bent around the DRA to increase the half-power beam width (HPBW) and the gain on H-plane, moreover, to improve the pattern on E-plane. The ground plane of the invention is further bent in different angles to reshape the radiation pattern of the dielectric resonator antenna, and a well is carved in the dielectric resonator antenna to increase its radiation bandwidth. The invention can also be adjusted as WiMAX sectorial antenna.
