Abstract
A calibration system for calibrating an antenna array comprising antenna elements comprises a measuring unit, and a calibration antenna connected to the measuring unit. The measuring unit sequentially excites each antenna element of the antenna array with an input signal and receives the corresponding output signal through the calibration antenna. Furthermore, the measuring unit measures a transfer function of each antenna element of the antenna array.
