Two Elements Ultra Wideband MIMO Antenna for 5G Communications, WiFi-5 and WiFi-6 Applications
In this paper, a two elements wideband MIMO antenna is proposed for 5G communications, WiFi-5, and WiFi-6 usage working in 3.89 GHz to 19.51 GHz frequency bandwidth with an FBW of 133.5 %. The antenna is composed of two identical rectangular patches, each with a circular slot, along with an E-shaped parasitic patch inside the slot. Also, an elliptical shape partial ground plane has been utilized to improve the impedance bandwidth of the suggested antenna. This design covers the n80 5G band (4.4 GHz – 4.99 GHz), and the complete bandwidth of both WiFi-5 and WiFi-6 (5.15 – 7.125) GHz. The mutual decoupling of the suggested MIMO antenna is below −20 dB over the whole frequency range. The proposed MIMO has an admirable correlation coefficient (ECC < 0.05), and the maximum channel capacity loss is 0.3 b/s/Hz. The proposed antenna has been simulated using HFSS software.
