In order to achieve very high throughput, VHT, high SINR for high M-ary QAM has to be achieved.? That implies actively beamforming connectivity between transmitter and receiver.? Beamforming is a product of antenna array design, where inter element phase shifting occur during the operation.

Ferrite phase shifters have been used in legacy Phased Array Antennas for military applications and are very expensive.? Commercial market has been using Diodes, MEMS and LCD for 5G beamforming.? The following table summarizes the comparison between these options.

Diodes, LCD, MEMS 5G BF Comparison

?

The comparison above table is based on the current technology and there are innovative techniques that can overcome some of the shortcoming depending on appropriate trade-offs.
