Transmitter tracking systems and methods are provided that utilize a phased array antenna. With the antenna forming a beam that is pointed in a first direction for a first frequency, a plurality of radio frequency (RF) signals, each associated with different carrier frequency and produced by a first transmitter, are received. The amplitudes of the received signals are used to determine whether the beam is pointed at the first transmitter. The amplitude information can also be used to determine a direction in which to point the beam if it is determined that the beam is not pointed at the first transmitter. The systems and methods can be applied to 5G, satellite communication, or other systems incorporating a phased array antenna.
