Abstract: In this article, a novel offset microstrip line feed Rectangular Dielectric Resonator Antenna is used for bandwidth enhancement. The parameters such as Bandwidth, Return Loss and Radiation efficiency are improved in the proposed antenna. A comparison is also shown for the proposed feed structure with and without conformal strips. The improvement in the bandwidth is observed from 25% to 65% by optimizing the antenna design parameters. It works in three frequency bands, that is, 2.03-3.69 GHz, 3.86-7.26 GHz, and 7.32-9.26 GHz. The proposed antenna is appropriate for WIMAX/WLAN applications.
