Ultra-wideband dielectric-resonator antenna based on hybrid techniques

In this paper, two configurations of dielectric resonator antennas designed by using hybrid techniques are proposed and compared. Hybrid resonators along with dielectric shaping and impedance matching methods are served to effectively excite a family of monopole-like radiation inside the dielectric. In the second antenna, a composite configuration is also applied to improve the matching at higher parts of the frequency bandwidth. Clearly, simulation results show an effective ultra-wide bandwidth of more than 10 GHz ranging from 1.8 GHz to 12 GHz. Furthermore, the radiation pattern of the proposed antenna is nearly omni-directional over the operating frequency bandwidth.
