Abstract
A phased array antenna system includes an array of antennas having first antenna and second antennas disposed equidistantly from a third antenna. The first antenna is associated with a first gain and a first phase and the second antenna is associated with a second gain and a second phase. The first antenna receives a first reference signal corresponding to a calibration reference signal transmitted by the third antenna, and the second antenna receives a second reference signal corresponding to the calibration reference signal transmitted by the third antenna. The second receiver module is configured to adjust the second gain and the second phase associated with the second antenna to match the first gain and the first phase associated with the first antenna by comparing the first reference signal received by the first antenna with the second reference signal received by the second antenna.
