Abstract

In this paper, a novel MIMO antenna system is proposed and studied for the application of 5G cell phone in the Sub-6 GHz frequency band. The configuration of the designed antenna consists of four resonators operating at the Sub-6 GHz 5G band. Each antenna element is composed of a planar-inverted F antenna (PIFA), a monopole antenna and a slot by defected ground structure (GDS). These four compact resonators are located in four corners, representing a smartphone board in practice. All radiating elements are etched on a low-cost FR4 substrate with an overall size of $150\times 75\times 7\mathrm{mm}^{3}$. Under the impedance matching ($S_{11}\leq$-10dB) of 3.3-5.8 GHz, the designed MIMO antenna has good total efficiency of 55%-87%, sufficient maximum gain of 3.5-6.0 dBi and ports isolation $\leq$-15dB. The bandwidth of the presented antenna covers Sub-6 GHz 5G band of some current research hotspots including n77(3.3-4.2GHz), n78(3.3-3.8GHz), n79(4.4-5.0GHz) and others. The calculated antenna envelope correlation coefficient (ECC) and total active reflection coefficient (TARC) are low over the whole band. Moreover, the proposed design exhibits very small specific absorption rate (SAR) values at the reflection zeros of user-head.

6ghz以下手机宽带MIMO天线系统

本文针对5G手机在sub - 6ghz频段的应用，提出并研究了一种新型MIMO天线系统。设计天线的配置由四个谐振器组成，工作在Sub-6 GHz 5G频段。每个天线单元由一个平面倒F天线(PIFA)、一个单极天线和一个缺陷接地结构(GDS)槽组成。这四个紧凑的谐振器位于四个角落，代表了实践中的智能手机板。所有辐射元件都蚀刻在整体尺寸为$150\times 75\times 7\mathrm{mm}^{3}$的低成本FR4基板上。在3.3-5.8 GHz的阻抗匹配($S_{11}\leq$ -10dB)下，所设计的MIMO天线具有良好的总效率55%-87%, sufficient maximum gain of 3.5-6.0 dBi and ports isolation $\leq$-15dB. The bandwidth of the presented antenna covers Sub-6 GHz 5G band of some current research hotspots including n77(3.3-4.2GHz), n78(3.3-3.8GHz), n79(4.4-5.0GHz) and others. The calculated antenna envelope correlation coefficient (ECC) and total active reflection coefficient (TARC) are low over the whole band. Moreover, the proposed design exhibits very small specific absorption rate (SAR) values at the reflection zeros of user-head.
