Abstract

See full text

To minimize a measurement range when a near field measurement is performed on the directivity of a massive-MIMO antenna, and prevent the accuracy of measurement from deteriorating. Beam direction detection means 33 causes a probe antenna 12 to perform a rough scanning in a state where an electromagnetic wave radiation plane 1a of a test antenna 1 is directed toward a reference direction directly facing a measurement plane P, and detects the direction of a beam radiated by the test antenna 1 on the basis of a received signal thereof. Antenna direction change means 34 changes the direction of the test antenna 1 so that the detected direction of a beam is directed toward the center of the measurement plane P.
