Abstract

Field probe for conducting antenna measurements by phaseless measurements. An antenna arrangement comprises three or four antennas for measuring RF waves. The measured RF waves are pairwise added and subtracted. Based on the result of the adding and subtracting operations, magnitude patterns and phase patterns are determined. In this way, magnitude and phase patterns of electromagnetic waves emitted by a device under test can be determined by a completely passive device.
