摘要

本文提出了一种用于第五代(5G)毫米波(MMW)应用的新型双元超宽带(SWB)、多输入多输出(MIMO)天线。单单元天线由一个圆形和一个梯形段组成，通过带部分地平面的锥形微带线馈电形成新的贴片形状。提出了一种尺寸为22 mm $\times$ 34 mm $\times$ 1.6 mm的双单元MIMO天线。为了保证两个端口之间的高度隔离，在公共接地面上引入了倒l型插脚，插脚长度为矩形。▼SII| $\leq$ -10dB的工作频段为3.2 GHz ～ 50 GHz(带宽为176)% and a bandwidth ratio of 15.62:1) with isolation of 19 dB(22dB for most of the operating band from 10 to 50 GHz), a high realized gain of 6.3 dB, and good radiation efficiency of 71.2% over the whole SWB frequencies. The obtained results in terms of performance are compared to other studies reported in the recent literature.

Compact Super Wideband Two-element MIMO Antenna for 5G Millimeter-Wave Applications

A novel two-element super-wideband (SWB), multiple-input multiple-output (MIMO) antenna for fifthgeneration (5G) millimeter-wave (MMW) applications is presented in this work. The single-element antenna is composed of one circular and one trapezoidal segment to create a new patch shape feeding by a tapered microstrip line with a partial ground plane. A two-element MIMO antenna with dimensions of 22 mm $\times$ 34 mm $\times$ 1.6 mm is proposed. To ensure high isolation between the 2 ports, inverted L-shaped stubs with a rectangular cut are introduced into the common ground plane. The operating frequency band for |SII|$\leq$-10dB is from 3.2 GHz to 50 GHz (bandwidth of 176% and a bandwidth ratio of 15.62:1) with isolation of 19 dB(22dB for most of the operating band from 10 to 50 GHz), a high realized gain of 6.3 dB, and good radiation efficiency of 71.2% over the whole SWB frequencies. The obtained results in terms of performance are compared to other studies reported in the recent literature.
