5G Mobile Antennas: MIMO Implementation

In the future generation of communication networks, a large amount of access points, i.e. antennas, will have to be deployed, on top of the existing ones, to support the exponential rise in traffic demand. MIMO, Massive MIMO and phased array technologies can provide networks with an enhanced capability for increased data throughput and high data integrity through path diversity, spatial multiplexing and beamsteering/beamforming techniques. Thus, in the present paper, we give a brief an overview of aforementioned technologies, implementation challenges and discuss the the related health concerns effect.
