Performance Comparison of Hybrid Switch, Phase Shifter and Lens Network over Hybrid Beamforming in Millimeter Wave Massive MIMO [PDF]

Iranian Journal of Electrical and Electronic Engineering
Due to cost and energy concerns with digital beamformers, much of the beamforming is done by hybrid beamformers in mm-wave (mm) massive multiple input multiple output (MIMO). Various works in hybrid beamforming structures considered either phase shifters,

Beamforming with hybrid reconfigurable parasitic antenna arrays

IEEE Transactions on Wireless Communications
A parasitic reconfigurable antenna array is a low-power approach for beamforming using passive tunable elements. Prior work on reconfigurable antennas in communication theory is based on ideal radiation pattern abstractions. It does not address the problem of physical realizability.
