Abstract
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.
