Novel S shaped dielectric resonator antenna for wireless communication

A novel S shaped dielectric resonator antenna for wireless communication is proposed. The proposed configuration is achieved by making two symmetrical U shape notches on conventional rectangular dielectric resonator antenna (RDRA). It lowers down the quality factor and thus, improves bandwidth significantly. The optimum dimension of these notches excites the fundamental TE111 like mode of the conventional RDRA. The fundamental mode has a broadside pattern which radiates in the direction normal to the ground plane.
