Gain Enhanced UWB Dielectric Resonator Antenna
An ultra-wideband dielectric resonator antenna (DRA) with enhanced gain is presented and investigated for wireless applications. The antenna has a compact shape with UWB characteristics. The radiators structure is a split Z-shaped DRA with dielectric constant (εr) of 10. The antenna is mounted on a copper ground plane of size 75 × 90mm2 and is fed by a split bevel-shaped strip to improve the impedance matching. Also, an air gap has been introduced between DR and ground plane to reduce the Q factor and dielectric constant, which in turn improves the impedance bandwidth. Extensive parametric studies have been carried out on different parameters in order to achieve an optimum structure. Ansoft HFSS v14 has been used for the simulation of the proposed antenna. The simulated results show that the antenna can efficiently operate over the frequency range from 2.5 GHz to 10.6 GHz covering the entire UWB range.
