Abstract

In this paper, a dielectric resonator antenna (DRA) with high gain and wide impedance bandwidth for fifth-generation (5G) wireless communication applications is proposed. The dielectric resonator antenna is designed to operate at higher-order TEδ15x mode to achieve high antenna gain, while a hollow cylinder at the center of the DRA is introduced to improve bandwidth by reducing the quality factor. The DRA is excited by a 50Ω microstrip line with a narrow aperture slot. The reflection coefficient, antenna gain, and radiation pattern of the proposed DRAs are analyzed using the commercially available full-wave electromagnetic simulation tool CST Microwave Studio (CST MWS). In order to verify the simulation results, the proposed antenna structures were fabricated and experimentally validated. Measured results of the fabricated prototypes show a 10-dB return loss impedance bandwidth of 10.7% (14.3-15.9GHz) and 16.1% (14.1-16.5 GHz) for DRA1 and DRA2, respectively, at the operating frequency of 15 GHz. The results show that the designed antenna structure can be used in the Internet of things (IoT) for device-to-device (D2D) communication in 5G systems.

摘要

本文提出了一种用于第五代（5G）无线通信应用的具有高增益和宽阻抗带宽的介质谐振器天线（DRA）。该介质谐振器天线设计为在高阶TEδ15x模式下工作以实现高天线增益，同时在DRA中心引入一个空心圆柱体，通过降低品质因数来提高带宽。DRA由具有窄孔径缝隙的50Ω微带线激励。使用商用全波电磁仿真工具CST微波工作室（CST MWS）分析了所提出的DRA的反射系数、天线增益和辐射方向图。为了验证仿真结果，制作了所提出的天线结构并进行了实验验证。所制作原型的测量结果表明，在15GHz的工作频率下，DRA1和DRA2的10dB回波损耗阻抗带宽分别为10.7%（14.3 - 15.9GHz）和16.1%（14.1 - 16.5GHz）。结果表明，所设计的天线结构可用于5G系统中的物联网（IoT）设备到设备（D2D）通信。
