摘要

本文提出了一种用于未来第五代(5G)智能手机应用的3.5 GHz多输入多输出(MIMO)天线系统。天线覆盖整个3.5 GHz/ c频段(3400 - 3600mhz)。该系统由四个尺寸分别为15 × 5 mm2和6 × 5 mm2的L型单极天线组成，分别安装在尺寸为100 × 55 × 1.6 mm3的FR-4基板的四个角上。为了增加电长度和减少天线之间的相互耦合(增加隔离)，通过部分去除顶部散热器板下方的接平面，在接平面上创建槽和缺口。对于设计的系统，可以实现75%以上的高效率、可接受的包络相关系数(ECC)(小于0.1)和任意两根天线的互耦(小于-11 dB)。在CST MWS中对该天线进行了建模和仿真。

A Four-Port Multiple Input Multiple Output (MIMO) Antenna for Future 5G Smartphone Applications

This paper presents a 3.5 GHz multiple-input multiple-output (MIMO) antenna system for the future fifth-generation (5G) smartphone applications. The antenna covers the entire 3.5 GHz/C-band (3400–3600 MHz). The proposed system consists of four identical L shape monopole antennas each with the dimensions of 15 × 5 mm2 and 6 × 5 mm2 installed on four corners of FR-4 substrate with dimensions of 100 × 55 × 1.6 mm3. In order to increase the electrical length and reduce mutual coupling (increase isolation) between antennas, slots and notches are created in the ground plane by partially removing the ground plane underneath the top radiator plate. For the designed system good efficiency more than 75%, acceptable envelop correlation coefficient (ECC) (less than 0.1) and mutual coupling (less than -11 dB) for any two antennas are achieved. The modeling and simulation of the proposed antenna are conducted in CST MWS.
