Because the size of antennas is defined by wavelengths, higher frequencies mean smaller antennas, so a 64×64 system for more typical cellular frequencies would be too big to be practical. Sprint ...
“This study presents a simple, miniaturized, and low-profile multiple-input multiple-output (MIMO) antenna operating at 29 GHz with reduced mutual coupling between the antenna elements for futuristic ...
