Description
Summary:In this paper, a new dielectric resonator antenna (DRA) is presented and investigated for ultra wideband (UWB) applications. The UWB antenna has a U-shape and excited by a microstip fed monopole. The proposed antenna was simulated and designed using two electromagnetic simulators. To validate our design, a prototype antenna was fabricated and measured. From the measurements, the U-shaped DRA has a 117.6% impedance bandwidth (from 2.94 GHz to 11.34 GHz, for return loss below -10 dB, largely covering the UWB spectrum band). Moreover, the proposed antenna provides an omni-directional radiation pattern. With these features, the present antenna can be used in ultra-wideband wireless systems.
