Abstract
A system for calibrating radio frequency test chambers is provided. The system comprises an antenna array with a plurality of antenna elements arranged in a three dimensional configuration, a plurality of power measuring units downstream to the plurality of antenna elements and a processing unit. In this context, the plurality of power measuring units output a power from each antenna elements corresponds to a radiation pattern generated by an incident test signal. The processing unit is configured to analyze the power distribution of the test signal in order to calculate a calibration.
