Abstract

In this paper, six-port MIMO antenna is presented for 5G mobile handsets. The proposed six-port antenna array is designed by making four L shaped monopole slots at four corners and two at the middle side edges of the ground plane which is printed on the backside of 0.8 mm thick FR4 substrate. High isolation (>−18 dB) between any pair of antenna elements is achieved without deploying dedicated isolation enhancing mechanisms. The antenna is working from 3.4–3.6 GHz (LTE Band 42) with 200 MHz bandwidth in the 2:1 VSWR (−10 dB impedance bandwidth). The proposed six-port MIMO antenna array is fabricated and measured. Significant radiation efficiency is obtained from 70 to 74 % in desired band of operation. Further, the MIMO parameters such as Envelope Correlation Co-efficient (ECC), Channel Capacity, Channel Capacity Loss (CLL) and Total Active Reflection Co-Efficient (TARC) are calculated. The robustness of the antenna is estimated by analyzing the user hand effects and Specific Absorption Rate (SAR). The measured results are well agreed with the simulated results.
