摘要

本文提出了一种将缺陷接地结构(DGS)与线谐振器结合的新方法，以减少h平面结构中线性阵列$2 × 1$天线的相互耦合。DGS和Line Resonator都设计用于阻挡两个天线的表面波，这两个天线的工作频率为2.6 GHz，边缘到边缘距离元件间距为$0.049 \lambda\ mathm {o}$。研究了设计实现前后天线的性能。仿真结果表明，天线间的耦合隔离度提高了- 11.84 dB，天线增益提高了0.191 dBi，旁瓣电平降低了2.5 dB。本设计具有带宽宽、结构紧凑、易于制造等优点，可用于s波段5G通信的大规模多输入多输出(M-MIMO)系统。

A Combination of Defected Ground Structure and Line Resonator for Mutual Coupling Reduction

In this paper, a new combination method of Defected Ground Structure (DGS) and Line Resonator to reduce mutual coupling in linear array $2\times 1$ antenna in H-plane structure is proposed. Both DGS and Line Resonator are designed to block surface waves of two antennas that work on a frequency of 2.6 GHz with an edge-to-edge distance element spacing is $0.049 \lambda\mathrm{o}$. The antenna performances before and after design implementation have been investigated. The simulation results show the coupling isolation between the antennas has been improved by −11.84 dB, the gain of the antenna increase by 0.191 dBi, and drop the side lobe level by 2.5 dB. The purposed design has the advantage of wide bandwidth, compactness and easy to fabricate, so it could be used for massive multiple-input multiple-output (M-MIMO) system for 5G communication in S-Band frequency.
