摘要：

In this paper, a novel multi-functional reconfigurable dielectric resonant antenna is proposed. It consists of a cylindrical and a sectored resonator structures, realizing the reconfigurable on polarization and radiation pattern simultaneously. Improved hybrid orthogonal network is used for feeding to provide a stable phase difference over 5 to 6 GHz band. The simulation results show that the linear polarization has an input reflection coefficient bandwidth of 22.8%, the circularly polarized has an input reflection coefficient bandwidth of 18.1%, and a 3-dB AR bandwidths of 6%. Benefited from the combination of dielectric resonant antenna with the reconfigurable structure, the design has high degree of design freedom and easy to be miniaturized.
