Abstract

This work proposes a four-port MIMO square patch antenna for 5G Internet of Things (IOT) applications. A Spilt Ring Resonator (SRR) is etched on the ground construction to boost the antenna's performance. The antenna's bandwidth is increased as a result of SRR. The proposed MIMO antenna has a 60*60 mm dimension at 24GHz radio Frequencies. The antenna is mounted on a 1.6 mm thick FR4 substrate. The developed antenna has a broadband function at 24–30 GHz, which is suitable for 5G applications, as per the ANSYS simulated results in this proposed work. Antenna properties such as reflection coefficients Snn −10dB, transmission coefficients Snm −20dB, gain, axial ratio, and radiation pattern are all simulated. Furthermore, for the full range frequency, the Envelope Correlation coefficients (ECC) for the proposed four port MIMO antenna design are less than 0.015. From the mathematical analysis and simulation results, the proposed MIMO antenna is better selection for 5G application with improvement is optimal stability transmission.

面向5G应用的SRR接地结构4端口MIMO天线设计

这项工作提出了一种用于5G物联网(IOT)应用的四端口MIMO方形贴片天线。为了提高天线的性能，在地面结构上蚀刻了一个分环谐振器(SRR)。由于SRR，天线的带宽增加了。所提出的MIMO天线在24GHz无线电频率下具有60*60 mm的尺寸。天线安装在1.6 mm厚的FR4基板上。根据ANSYS仿真结果，所开发的天线具有24-30 GHz的宽带功能，适合5G应用。天线的反射系数Snn−10dB、透射系数Snm−20dB、增益、轴比和辐射方向图等特性都进行了仿真。此外，对于全范围频率，所提出的四端口MIMO天线设计的包络相关系数(ECC)小于0.015。从数学分析和仿真结果来看，所提出的MIMO天线是5G应用的较好选择，提高了传输的最优稳定性。
