Wideband miniaturized 8-element sub-6 GHz MIMO antenna system for mobile handset applications

Abstract

An 8-port MIMO antenna system covering the band of 3–6 GHz for the 5G MIMO mobile handset applications is proposed. The antenna element consists of an open-slot antenna and a T-shaped feeding strip. Also, an L-shaped strip is adopted to improve the impedance bandwidth and achieve miniaturization simultaneously. The measured results show that wide impedance bandwidth, high isolation (>11 dB), high efficiency (>40%) and lower ECC (<0.1) are realized. Finally, the hand-grip effects are investigated by simulation to verify its capability for the industrial applications.
