Abstract

A dielectric resonator antenna with a T-slot configuration based on substrate integrated waveguide is proposed for a 3.5 GHz 5G application. A SIW structure with a T slot is etched on the top surface plane of the Rodger 5880 substrate, and the dielectric resonator is then mounted to the T-slot. A 50-ohm coaxial cable is used to feed the antenna, placed at the appropriate position. The performance analysis of a dielectric resonator antenna with T slot configuration supported by substrate integrated waveguide (SIW) has been investigated. Parametric studies on various parameters to improve the performance in terms of gain, impedance bandwidth, surface current, and impedance matching behaviors are observed. The simulated result of the proposed dielectric resonator antenna supported by SIW shows a reflection coefficient of more than 10 dB in desired frequency at 3.5 GHz which is in good agreement with the simulated results. In this study, the gain of the T-slot antenna was 5.01 dB. All simulations are done using Computer Simulation Technology (CST) software. The designed antenna structure with specified materials and related values respectively makes it a potential candidate for future 5G particularly for sub-6 GHz technology.

基于基板集成波导的5G T槽介质谐振器天线性能分析

提出了一种基于衬底集成波导的t槽介质谐振器天线，用于3.5 GHz 5G应用。在Rodger 5880衬底的上表面平面上蚀刻带有T槽的SIW结构，然后将介电谐振器安装在T槽上。50欧姆同轴电缆用于馈电天线，放置在适当的位置。研究了衬底集成波导支持的T槽介质谐振器天线的性能。在增益、阻抗带宽、表面电流和阻抗匹配行为方面，对各种参数进行了参数化研究，以提高性能。仿真结果表明，在3.5 GHz的期望频率下，SIW支撑的介质谐振器天线的反射系数大于10 dB，与仿真结果吻合较好。在本研究中，t槽天线的增益为5.01 dB。所有的模拟都是使用计算机仿真技术(CST)软件完成的。设计的天线结构分别具有指定的材料和相关值，使其成为未来5G特别是低于6 GHz技术的潜在候选者。
