摘要

本文提出了一种用于c波段(3.4GHz - 3.8GHz) 5G通信系统的带槽和部分地平面的四元MIMO天线。它是在Rogers RT/ period 5880上设计的，介电常数和厚度分别为2.2和0.787mm。在不使用去耦结构和额外间距的情况下，采用Hill - Climbing启发式搜索算法对天线槽和部分地平面的尺寸进行优化，以增加天线单元之间的阻抗带宽和减少相互耦合。在S11≤-10dB时实现了539.4MHz的巨大带宽，覆盖3.2926 ~ 3.832GHz，在3.595GHz处谐振，反射系数和互耦合分别为-46.45dB和< -16dB。在整个工作频带内，包络相关系数(ECC) < 0.017，分集增益(DG) < 10dB，信道容量损失(CCL) < 0.18bits/sec/Hz。

A Slotted MIMO Antenna for 5G C-band Communication Systems

In this paper, a four-element MIMO antenna with slots and partial ground plane for 5G communication systems operating at C-band (3.4GHz - 3.8GHz) is presented. It is designed on Rogers RT/Duriod 5880 with a dielectric constant and thickness of 2.2 and 0.787mm, respectively. The dimensions of the slots and the partial ground plane are optimized by applying a heuristic search algorithm, the Hill Climbing, to increase the impedance bandwidth and reduce the mutual coupling between the antenna elements without using a decoupling structure or extra spacing. It achieves a huge bandwidth of 539.4MHz covering 3.2926GHz to 3.832GHz at S11 ≤ -10dB and resonates at 3.595GHz with a reflection coefficient and mutual coupling of -46.45dB and < -16dB, respectively. It also achieves an envelope correlation coefficient (ECC) of < 0.017, diversity gain (DG) of ~10dB and channel capacity loss (CCL) of < 0.18bits/sec/Hz throughout the operating frequency band, respectively.
