Abstract
An electric field intensity distribution measurement devicethat measures, in a near field, a radio signal transmitted from an antennaincluding a plurality of antenna elements Tto TN integrated into a transmission deviceincludes a measurement antennathat receives the radio signal as a measurement signal at a plurality of scanning points included in a predetermined scanning range, a reference antennathat receives the radio signal as a reference signal, a phase difference and amplitude calculation unitthat calculates a phase difference between a measurement signal and a reference signal with respect to each scanning point, and an amplitude of the measurement signal, and a far-field electric field intensity distribution calculation unitthat calculates an electric field intensity distribution in a far field using information on the phase difference and the amplitude calculated by the phase difference and amplitude calculation unit
