Dual Beam/Multibeam Antennas,sed in Chap. ., the MIMO with beamforming can have much better performance than traditional MIMO techniques at mmWaves. Multibeam antennas generate multiple radiation beams to cover predefined angular space and provide added advantage as compared to single beam antennas.

Beam Switching and Wide-Scan Antenna Array,The previous Chapter describes how the beam tilting antennas with fixed radiation beam helps to maintain the line-of-sight wireless link. However, millimetre wave indoor communication is not necessarily LOS but can be both LOS and non-LOS and to maintain the communication link requires a smart antenna system having beam switching capabilities.

Millimeter Wave Lens Antennas,Millimetre waves can provide exploding capacity demands for next generation wireless systems. Also due to the short wavelengths, full dimensional massive MIMO operation becomes possible as large number of antennas can be packed in a small form factor.
