Abstract
A method and a system for calibrating an antenna array. The method may include the following steps: attaching successively pairs of a plurality of probe antennas to each other; performing an initial measurement of a multiport formed by the ports of said pair of probe antennas, the initial measurement yielding initial coefficients of said probe antennas; attaching successively one of said probe antennas to one of the antennas in said antenna array; performing a second measurement of multiports formed by the ports of said probe antennas and said antenna array, the second measurement yielding coefficients of the combination of said antenna array and said probe antennas; and using the initial coefficients and the second measurement coefficients to calibrate said antenna array.
