MM wave MIMO antenna system for UE of 5G mobile communication: Design

This proposal presents a design of compact MIMO antenna array for a mobile phone to be used in 5G cellular mobile communication. Main focus of this work is to design an MIMO antenna system which can resonate at particular frequencies as per the requirement. A mobile handset antenna supporting wide frequency range is essential exploratory issue. This paper manifests an antenna resonating at 1.5GHz, 2.2 GHz and 28 GHz frequency in the wide upper band 10-30 GHz, which is an expected resonance frequency for future 5G mobile communication. Gain value of 6.622 dBi, 7.35 dBi, and 6.01 dBi at 28 GHz, 2.2 GHz, and 1.5 GHz respectively, are achieved. Higher frequency radiation effect will be more on user, so radiator is placed at bottom edge of the mobile system board. SAR values at different frequencies: at 2.2 GHz it is 0.471 W/Kg, at 1.5 GHz value is 0.205 W/Kg.
