摘要：In this paper, an elliptical slot fed hexagonal shaped dielectric resonator antenna (DRA) with wideband operations is presented. The Elliptical slot represents the coupling mechanism between the resonator and the micro strip line, and the micro strip feed line is positioned at right angle to the center of the slot for efficient coupling. The DRA and slot are both resonant structures, and together yield double resonant structures with low cross polarization levels and identical radiation pattern. With proper design, the two resonances can be merged to achieve wide bandwidth. A comprehensive parametric study is carried out to analyze the characteristics of the proposed antenna. Simulation results show that the proposed DRA has a 10 dB impedance bandwidth of 47.53% from 2.2446 GHz to 3.8098 GHz.
