摘要：
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 300, 600, 1200 angular portion of cylinder with radius ratio (1:2:3). Stacking of Rogers 3010 (epsilon(r) = 10.2) and FR-4 (epsilon(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 HE11 delta, HE12 delta modes are identified at 4.43 GHz & 8.31 GHz resonant frequencies respectively.
