A high-gain hybrid monopole dielectric resonator antenna is proposed. The bridge-shaped dielectric resonator is selected as radiator, which works in high-order modes. The monopole excites the DR as the feeding mechanism and also acts as an effective radiator itself. The bandwidth of 46.6% at the centered frequency of 4.85GHz and the gain of over 8dBi for the entire operational bandwidth have been achieved. An enhancement of gain by over 3dBi has been obtained compared to a single monopole antenna mounted on the ground plane.
