Abstract
The system includes a plurality of probe antennas that receive radio signals at a plurality of measurement positions located within a measurement plane in a near field region of an antenna to be measured, a probe scanning mechanism that moves the respective probe antennas to a plurality of measurement positions while maintaining relative positions of the plurality of probe antennas, an amplitude and phase difference measurement unit that measures a phase difference between the radio signals and measures amplitudes of the radio signals, every time the respective probe antennas are moved to the measurement positions, and a phase calculation unit that calculates a phase of the radio signal at each measurement position from the phase difference measured by the amplitude and phase difference measurement unit.
