  abstract={In this paper, we present eigenbeam measurements performed with our multiple-antenna demonstrator MASI. The existing angle offset of the estimated eigenbeams motivated calibration and verification measurements in an anechoic chamber. After eliminating the sources of errors via phase calibration this squinting is removed and the estimated direction-of-arrivals of the transmit signal become plausible. Additional measurements of a rotating receive array sustain the successful off-line phase calibration.
