Multi Antenna systems such as beamforming and MIMO are anticipated to play a key role in 5G and beyond 5G communications. The Phased Array Antennas(PAAs) with phase shifter is the dominant method to achieve beamforming up to now. However the operation bandwidth of PAAs is limited to narrow(~200MHz)...
