Abstract
An antenna array calibration device and method thereof are provided. The method includes measuring the power total of the antenna array, controlling active components to adjust the antennas to having a maximum amplitude, controlling phase shifters to adjust the antennas to having a random phase, calculating the phase difference between an initial phase and a random phase, calculating the amplitude difference between an initial amplitude and the maximum amplitude, introducing the phase difference, the amplitude difference and the power total of the antenna array into a simultaneous equation of amplitudes and phases to obtain the initial amplitude and the initial phase of the antennas, and adjusting the phase of the antenna array if there is a real number solution of the equation, or otherwise adjusting the phase of the antenna array to another random phase to obtain a real number solution of the equation.
