Antenna Designs for a Milimeter Wave Massive MIMO Testbed with Hybrid BeamformingView Publication
Massive multiple-input multiple-out (MIMO) technology and mm wave are important technologies in 5G/6G to enhance the spectrum efficiency and system capacity. However, it has a lot of challenges in mm wave range, such as high hardware cost and power consumption in such systems. Hybrid beamforming is an interesting solution with less number of RF transvers than antennas. In this paper, we will present antenna designs for a 28GHz hybrid beam forming massive MIMO system with 64 antennas and 16 RF transvers.
