摘要

多输入多输出（MIMO）天线设计一直是无线技术领域的热门话题。虽然多输入多输出天线有很多优点，但如何最大限度地减少天线元件之间的相互耦合是一个关键挑战。本研究为 LTE、WLAN 和 5G 应用提出了一种两个三频天线之间的去耦技术。对于 3.5GHz 频段，首先创建一个单极子；其他两个谐振频率则通过改变部分地平面来实现。然后，利用两个三频单极子创建 MIMO 天线系统。低频段的谐振器可以通过抑制表面波传播，将两个高频段的相互耦合降至最低。最后，通过使用分环谐振器（SRR）来抵消原有的耦合，从而降低低频段的耦合。报告的 MIMO 天线横跨 2.4/5.8GHz WLAN 和 LTE 频段，以及 3.5GHz 5G 频段，相互耦合小于 -18dB。

A Decoupling method using Split Ring Resonator (SRR) for Tri-band MIMO Antenna for WLAN LTE Band and 5G applications

MIMO antenna design has always been a topic of interest in wireless technology. Although it has many benefits, the key challenge is to minimize mutual coupling between antenna elements. This study presents a decoupling technique between two tri-band antennas for LTE, WLAN, and 5G applications. For 3.5GHz, a monopole is initially created; the other two resonant frequencies are produced by changing the partial ground plane. Then, a MIMO antenna system is created using two tri-band monopoles. The resonators of low band can minimize the mutual coupling for two higher bands by suppressing surface wave propagation. Finally, coupling is reduced in the low band by using a Split Ring Resonator (SRR) to cancel out the original coupling. The reported MIMO antenna spans the 2.4/5.8GHz WLAN and LTE bands, as well as the 3.5 GHz 5G bands, with a mutual coupling of less than -18 dB.
