PROBLEM TO BE SOLVED: To provide an electromagnetic field property measuring system using a measured object loading pedestal which accurately measures radiation power in three-dimensional space of a heavy-weight measuring object. SOLUTION: This electromagnetic field property measuring system is constituted of a turntable which has azimuth shaft motor and roll axis motor to revolve around the azimuth shaft, and materials with relative permittivity of 1.5 or lower. The system is provided with first and second poles of three times or more length as the wavelength of measured electromagnetic field vertically, mounted at regular intervals on one side of the turntable, first pulley with relative permittivity of 3 or lower in which a central axis is run through upper end section of the first pole to be the roll axis; second pulley with relative permittivity of 3 or lower to be mounted on upper end section of the second pole spaced with the first pulley by 1/2 times or larger length as the wavelength; an arm with relative permittivity of 1.5 or lower to be mounted on the area between the first pulley and the second pulley, in parallel with the turntable; and a belt with relative permittivity of 4 or lower connecting the central axis of the first pulley to the roll axis motor.
