Design of Wide-beam Hybrid Monopole Dielectric Resonant Antenna

In this paper, a wide-beam hybrid monopole dielectric resonant antenna is proposed. A broad beam radiation pattern over the entire frequency range is achieved by the dielectric loading technique on the basis of a broadband monopole antenna. The simulated results show that the antenna achieves a relative bandwidth of 39.3%, and the half-power beamwidth (HPBW) can achieve a wide-beam coverage of 120° in E-plane and H-plane in the frequency range of 14.1 GHz-17.6 GHz.
