Orthogonal Quad-Port Wearable MIMO Antenna for Sub-6GHz 5G and WLAN/Wi-Max/Wi-Fi Applications

An orthogonal dual/quad port multi-in multi-out (MIMO) antenna configuration is proposed on wearable jeans material for wide band applications, such as sub-6GHz 5G and WLAN/Wi-Max/Wi-Fi applications. The proposed quad port MIMO antenna is wideband in nature with a frequency range of 2.58 GHz – 6.90 GHz (91.1%) is analyzed by using Ansys HFSS simulator. The wideband MIMO antenna of dual/quad-element is then introduced to address many practical challenges, such as electromagnetic wave scattering, shadowing, and multipath fading. To enhance isolation between radiating elements, antenna blocks are aligned orthogonally to get greater 20 dB isolation over the applications band. Measures of MIMO diversity include the ECC<0.1, DG>9.98, MEG<-6dB and CCL<0.1 bits/s/Hz are found within the acceptable range.
