Four-Element 8-Port Dual-band MIMO Antenna System for 5G Mobile Communication

A novel dual-band compact 8x8 MIMO antenna is proposed for 5G mobile communication. The lower band (3.3- 3.8) GHz is authorized for 5G as coverage and capacity band. The higher band is UWB band (5.2-6.8) GHz, which is used for directional data and requires 500 MHz bandwidth for greater accuracy. Along with dual band operation, the proposed design gives polarization and pattern diversity and can be incorporated in handsets for directional beams in 5G communication. Eight feeding ports are incorporated with four radiating structures, which saves space in handsets. The proposed design provides 380 MHz in lower band and 560 MHz in higher band, with overall radiation efficiency of 90%.
