This paper presents an 8-port MIMO antenna array for use with 5G handsets. The proposed MIMO antenna array comprises eight U-shaped, coupled-fed slot antenna components placed symmetrically on a 0.8 mm thick FR4 substrate. Each antenna has 200 MHz bandwidth and covers 3.4-3.6 GHz. The operational frequency range includes LTE band 48 for 5G cellular applications. Using spatial and polarisation diversity, antenna components are isolated by over 15 dB. The prototype antenna is fabricated and measured, and the experimental results agree with the simulated results. The estimated Envelope Correlation Coefficient (ECC), less than 0.035 based on radiation characteristics, shows that the suggested MIMO antenna array performs well in diversity. These characteristics indicate that the proposed MIMO antenna is a viable solution for 5G smartphone applications.
