摘要

本文介绍了一种新颖的三频多入多出（MIMO）天线设计方法。该天线由布置在两侧框架上的四组相同的天线对组成。通过在天线单元设计中采用不同的分支，使用微带耦合馈电结构可获得三种谐振模式。各模式的工作频率可独立调整。此外，在每对天线中，两个天线单元紧密排列，相邻天线之间采用去耦接地支路，以确保良好的隔离。三频八元件多输入多输出天线的工作频率为 3.5、4.9 和 5.6 千兆赫，隔离度优于 14 分贝。所提出的天线具有 0.06 λ 0 ${\lambda }_{0}$ 的低剖面和良好的隔离度，因此在 5G 移动终端中具有潜在的应用价值。

Compact multi-band eight-element MIMO antenna with decoupled antenna pairs for 5G mobile terminal applications

This paper presents a novel design method for a tri-band multiple in multiple out (MIMO) antenna. The antenna consists of four sets of identical antenna pairs arranged on the two side frames. Three resonant modes can be obtained using a microstrip coupling feed structure by employing different branches in antenna unit design. The working frequencies of the modes can be adjusted independently. Moreover, in each pair of antennas, two antenna units were closely arranged and a decoupling grounding branch was employed between the adjacent antennas to ensure good isolation. The tri-band eight-element MIMO antenna operates at 3.5, 4.9, and 5.6 GHz and the isolations were better than 14 dB. The proposed antenna had a low profile of 0.06 $λ_{0}$ and good isolation so it has potential applications in 5G mobile terminals.
