Phased array antenna

Phased array antennas are a means of creating narrow beams  and dynamically pointing them in the desired direction without  mmWave antennas used for 5G base stations and UEs. A  phased array antenna is formed by an array of smaller antenna  elements, such as individual patches or dipoles. By varying the  relative phases and amplitudes of the signals applied to the  individual elements, the antenna array can shape and steer a  beam in a chosen direction.
