PROBLEM TO BE SOLVED: To improve an antenna evaluation performance using a scatter antenna whose quantity and location are limited in evaluating a multi antenna.SOLUTION: A multi antenna evaluation device comprises: a path arrival direction setting value calculation portion 13 that calculates pass arrival direction setting value as a weight vector which is used to adjust level and phase of a transmission signal radiated from each of a plurality of scatter antennas by using an array directional characteristic vector in a desired path arrival direction with respect to a multi antenna of machine to be measured and a reference transmission characteristic matrices with respect to the multi antenna of the machine to be measured and the plurality of scatter antennas; and a level/phase adjustment portion 12 that adjusts level and phase of the transmission signal radiated from each of the plurality of scatter antennas by using the path arrival direction setting value. |
