摘要

在本研究中，描述了使用电磁带隙(EBG)和缺陷地结构(DGS)技术组合的8x8 MIMO微带天线结构的附加设计。通过技术的结合，有望抑制MIMO天线元件之间的相互耦合效应，从而提高天线隔离度，支持MIMO天线性能。本设计采用$\varepsilon_{r}=4.3$的FR-4环氧材料，在3.5 GHz频率下配置64个MIMO元件，用于5G c波段应用。仿真结果和天线测量结果表明，与不添加EBG和DGS结构相比，天线之间的隔离度有所提高。这些结果表明，在MIMO天线上使用EBG和DGS结构的组合可以改善隔离，从而有望提高5G技术应用的天线性能。

Combination of EBG and DGS to Improve MIMO Antenna Isolation

In this study, the design of the addition of an 8x8 MIMO microstrip antenna structure using a combination of electromagnetic band gap (EBG) and defected ground structure (DGS) techniques is described. Through the combination of techniques, it is expected to suppress the mutual coupling effect between MIMO antenna elements, thereby increasing antenna isolation that can support MIMO antenna performance. This design uses FR-4 epoxy material with $\varepsilon_{r}=4.3$ with 64 MIMO elements at 3.5 GHz frequency for 5G C-Band application. The simulation results and antenna measurements show an increase in the isolation between antennas compared to without the addition of EBG and DGS structures. These results indicate that the use of a combination of EBG and DGS structures on MIMO antennas can improve isolation which is expected to improve antenna performance for 5G technology applications.
