ム。[Claims for Utility Model Registration] (1) Consisting of a recorder, a test antenna connected to a receiver, and an opposing antenna arranged opposite to the test antenna and connected to an oscillator, By rotating the antenna under test or moving the opposing antenna, the relative phase of the radio waves transmitted simultaneously from the two apertures of the opposing antenna can be changed discontinuously and periodically. By rotating the test antenna or moving the opposing antenna in response to the change in amplitude at the receiver, and measuring the relative phase and amplitude with the recorder and performing arithmetic processing. , in the antenna measurement system for determining the phase characteristics of the test antenna, the opposing antennas include one pair of opposing antennas with a spacing of d and another pair of opposing antennas with a spacing of n×d (n is an integer). Antenna measurement system consisting of an antenna consisting of a pair of opposing antennas. (2) Three or more of the opposing antennas and a dummy load are provided, two of the opposing antennas are connected to a feeding system, and an opposing antenna that is not connected to the feeding system is connected to the dummy load. An antenna measurement system according to claim 1, characterized in that the antenna measurement system is equipped with a switch.
