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.
