Abstract
There is a provided a system for measuring an antenna radiation pattern in a Fresnel region, including: a fixed antenna and a movable antenna located in the Fresnel region to acquire a far-field radiation pattern; a moving unit for moving upward or downward to adjust a measuring angle of the movable antenna; a rotation unit to rotate a rotation shaft horizontally; a vector network analyzing unit 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 one of the fixed antenna and the movable antenna as a receiving antenna, and detecting a complex value; a control and communication unit for controlling the vector network analyzing unit and a control unit, and performing a data communication; and the control unit for providing a vertical/horizontal rotation force to the moving unit and the rotation unit under a control of the control and communication unit.
