摘要

本文介绍了一种适用于WiFi/WiMAX/ WLAN/蓝牙/ c波段通信/ 5g中期应用的双频MIMO天线。单天线单元在5.50 GHz和8.02 GHz左右表现出双谐振模式，实现了4.27 ~ 6.34 GHz和6.59 ~ 10.05 GHz两个工作频段。MIMO包括四个叉形散热器，垂直放置在1.6 mm宽的FR4材料上，尺寸为35 mm˟35 mm。MIMO的补丁被修改为具有3.78 - 6.47 GHz和6.47 - 9.5 GHz的阻抗带，其谐振频率为4.68,6.13和7.35 GHz。规划的MIMO天线在整个工作频带实现超过-23 dB(最大-45 dB)的隔离。所考虑的MIMO天线还具有低ECC(约0.04)，高分集增益(约10 dB)，最终增益为3.78 dBi，最大效率为81.8%。这些优点和特点使得预期的天线适用于WLAN/Bluetooth/WiMAX/WiFi/C-band/5G sub-6 GHz频段。

A Dual-band MIMO Antenna for 5G sub-6 GHz/WiFi/WiMAX/WLAN/Bluetooth/C-band Applications

This paper illustrates a dual-band MIMO antenna for WiFi/WiMAX/ WLAN/Bluetooth/C-band communication/ mid-5G applications. The single antenna element exhibits dual resonant modes at around 5.50 GHz and 8.02 GHz and achieved two working bands of 4.27 - 6.34 GHz and 6.59 - 10.05 GHz. The MIMO comprises four fork-shaped radiators orthogonally positioned on 1.6 mm wide FR4 material of size 35 mm ˟ 35 mm. The patches of the MIMO are modified to have an impedance band of 3.78 - 6.47 GHz and 6.47 - 9.5 GHz, which resonates at 4.68, 6.13, and 7.35 GHz. The planned MIMO antenna achieves more than -23 dB (maximum -45 dB) isolation throughout the working bands. The considered MIMO antenna also has a low ECC (around 0.04), high diversity gain (around 10 dB), an ultimate gain of 3.78 dBi, and a maximum efficiency of 81.8%. These advantages and features make the anticipated antenna appropriate for WLAN/Bluetooth/WiMAX/WiFi/C-band/5G sub-6 GHz bands.
