摘　　要：为了满足5G大规模MIMO技术的需求,文章提出了一种上层加载电磁超表面结构的四单元微带MIMO天线,其中上层加载的电磁超表面辐射能量通过改变微带天线的谐振结构改善了天线的性能,且任何端口隔离度均小于-15dB,完全符合工程实践要求。同时,文章利用专业电磁仿真软件HFSS对天线模型进行了详细分析和优化,并对实物模型进行了测试。仿真测试结果显示,该MIMO天线的10dB带宽达20.4%,远场辐射增益最大值为6.48dBi,能够应用于5G无线移动通信系统。In order to meet the requirements of 5G large-scale MIMO technology,this article proposes a four element microstrip MIMO antenna with an upper layer loaded electromagnetic metasurface structure,The radiation energy of the upper layer loaded electromagnetic metasurface improves the antenna performance by changing the resonant structure of the microstrip antenna,and the isolation degree of any port is less than-15 dB,which fully meets the requirements of engineering practice.Meanwhile,this article conducted a detailed analysis and optimization of the antenna model using professional electromagnetic simulation software HFSS,and tested the physical model.The simulation test results show that the 10 dB bandwidth of the MIMO antenna reaches 20.4%,and the maximum far-field radiation gain is 6.48 dBi,which can be applied to 5G wireless mobile communication systems.
