摘要

摘要:提出了一种用于实现圆极化辐射的双波段矩形介质谐振器天线(DRA)。该天线由带地平面的基板、矩形介电谐振器、超表面、圆形贴片和同轴探头组成。基板上的超表面可以实现圆偏振。矩形DR上的圆形贴片可以增加反射系数，实现双频工作模式。仿真结果表明，该系统具有24.7% (4.23 GHz ~ 5.42 GHz)和8.5% (5.60 GHz ~ 6.10 GHz)的双频段工作频率。此外，该天线具有5.60 GHz - 6.10 GHz频率范围内的圆极化，可广泛用于5G无线通信。本文提出的天线同时实现了介质谐振器天线的双频和圆极化。

A Dualband Dielectric Resonator Antenna over a Metasurface with Circular Polarization

Ahstract-A dualband rectangular dielectric resonator antenna (DRA) with a circular patch over a metasurface for achieving circularly polarized radiation is proposed. The proposed antenna is comprised of a substrate with ground plane, a rectangular dielectric resonator (DR), a metasurface, a circle patch, and a coaxial probe. The metasurface upon the substrate can realize the circular polarization. The circle patch upon the rectangular DR can increase the reflection coefficient and realize the dual-band working mode. Simulation results show that the proposed DRA has a dual band of operating frequency which is 24.7% (4.23 GHz - 5.42 GHz) and 8.5% (5.60 GHz - 6.10 GHz), respectively. Also, the antenna has a circular polarization in the frequency range 5.60 GHz - 6.10 GHz and it could be widely used for 5G wireless communication. The antenna proposed in this paper has achieved dualband and circular polarization of dielectric resonator antenna simultaneously.
