Abstract
There are provided methods and systems configured to perform calibration of antenna array systems, for example during production, avoiding the use of external setups or external measurements. The method comprising: (i) measuring the delay of a dedicated calibration transmission line for each SUT, for example during production, using internal built-in system capabilities; (ii) comparing the measured delay to a known delay of an identical transmission line of a reference system; (iii) computing, based on this comparison, compensation values with respect to the reference system of delay (or phase), for all transmission lines of the SUT; (iv) calibrating the SUT using the computed compensation values for all transmission lines of the SUT.
