1. A system for measuring an antenna radiation pattern in a Fresnel region, comprising:

  • a fixed antenna and a movable antenna located in the Fresnel region for acquiring a far-field radiation pattern;

    a moving means moving upward or downward, for adjusting a measuring angle of the movable antenna;

    a rotation means for rotating a rotation shaft horizontally;

    a vector network analyzing means for outputting an radio frequency (RF) signal to one of the fixed antenna and the movable antenna as a transmission antenna, receiving the RF signal received through the other as a receiving antenna, and detecting a complex value;

    a control and communication means for controlling the vector network analyzing means and a control means, and performing a data communication; and

    the control means for providing a vertical/horizontal rotation force to the moving means and the rotation means under a control of the control and communication means.
