Design of rectangular and hemispherical dielectric resonator antenna

Dielectric Resonator Antenna covers up the most essential characteristics like high efficiency, large bandwidth, compactness, high gain which are the essential criteria for antenna in today's world. The objective of proposed work is to compare two shapes of DRA, called Rectangular DRA and Hemispherical DRA. The change in result in both the shape of DRA are observed, which justifies the hemispherical DRA gives large BW compare to the rectangular DRA. Both antennas are designed for 2.4GHz and 5.4GHz frequency application.
