This work carries a novel miniaturized Dielectric Resonator Antenna (DRA) that has radiations in the broadside region. The antenna was designed and simulated using Advanced Design System (ADS) software. The antenna proposed consists of a solid ‘A’ shaped dielectric resonator mounted on the edge of the ground plane to reduce the overall volume and excited by using a microstrip feed line. An air gap is introduced between the resonator and the ground plane inorder to improve the bandwidth. This antenna showed a high efficiency & gain over the proposed radiating frequency. Experimental results show that the antenna radiates at a frequency of 8.9 GHz with a return loss of -19.93 dB. This antenna can also be used alongside with portable wireless devices.
