Abstract
An antenna system comprising (1) an array of antennas capable of beamforming and (2) at least one controller communicatively to the array of antennas, wherein the controller (A) collects a first set of measurements taken at each of the antennas as the antennas are activated individually, (B) collects a second set of measurements taken at each of the antennas as pairs of the antennas are activated together, (C) determines one or more inefficiencies in the beamforming of the antennas based at least in part on the first and second sets of measurements, and (D) calibrates the antennas to improve the beamforming by modifying one or more phase shifters of the antennas to compensate for the inefficiencies in the beamforming Various other apparatuses, systems, and methods are also disclosed.
