A Dual-band MIMO Antenna for Wi-Fi 6E / 7 System in a Small Base Station

In this article, a 6 × 6 MIMO patch antenna design is proposed for application in the dual-band Wi-Fi 6E / 7 system. This antenna model covers the Wi-Fi 6E / 7 frequency bands of 2.38-2.44 GHz and 4.9-7.125 GHz. And, the proposed antenna provides measured peak gains and antenna efficiencies close to 6.4 / 10 / 8.6 dBi and 75 / 80 / 70 % across the 2.45 / 5.5 / 6.5 GHz operating bands, respectively. Also, the measured envelope correlation coefficient (ECC) is less than 0.3 across the operating bands for the MIMO patch antennas.
