Abstract: A measurement system including an anechoic chamber, a turntable, N measurement antennas, in which N is a natural number and N?11, in which a spherical coordinate system is established by taking a center of a measured piece as an origin and a coordinates of the i (i=1, 2, 3, . . . , N) measurement antenna is Ai(?i, ?i, ?i), (i=1, 2, 3, . . . , N), in which ?i is a positive integral multiple of 15°, and at least one measurement antenna is arranged at a position where the angle ?is 15°, 30°, 30°, 45°, 60°, 75°, 90°, 105°, 120°, 135°, 150° or 165° correspondingly; and 0??i?360°, and the N measurement antennas are not located in the same plane. The present disclosure can create a measurement environment with small coupling interference and low reflection between the measurement antennas in a relatively small anechoic chamber, improving the measurement accuracy.
