Abstract
In this paper, a novel Fractal Cylindrical Dielectric Resonator Antenna (FCDRA) is presented for Ultra-Wide Band applications (UWB). The proposed antenna is constructed by 30°, 60°, 120°angular portion of cylinder with radius ratio (1:2:3). Stacking of Rogers 3010 $(\varepsilon_{\mathrm{r}}=10.2)$ and FR-4 $(\varepsilon_{\mathrm{r}}=4.4)$ dielectric materials are used in proposed antenna for enhancement of the bandwidth. This fractal geometry offers 9.2 GHz operating bandwidth which spans from 3.6 GHz - 12.8 GHz. Proposed antenna attains maximum gain of 9.45 dBi with more than 89% efficiency which is suitable for satellite communication, WiMAX application. Hybrid Electromagnetic $\mathbf{HE}_{11 \delta}, \mathbf{HE}_{12\delta}$ modes are identified at 4.43 GHz & 8.31 GHz resonant frequencies respectively.
