SYSTEM AND METHOD FOR MEASUREMENT OF ANTENNA RADIATION PATTERN IN FRESNEL REGION

摘要

A system for measuring an antenna radiation pattern in a Fresnel region which lies between near-fields and far-fields and a method thereof are provided to measure a far-field radiation pattern by varying the antenna measurement height up or down manually, thereby reducing the cost. A system for measuring an antenna radiation pattern includes a fixed antenna(10), a movable antenna(20), a vertical movement unit(30), a horizontal rotation unit(50), a vector network analysis unit(70), and a control unit(90). The vertical movement unit(30) moves the movable antenna(20) vertically for adjusting a measurement angle of the movable antenna(20). The vector network analysis unit(70) detects a complex value from an RF(Radio Frequency) signal received from a receiver antenna after transmitting an RF signal to the receiver antenna among the fixed and movable antennas(10,20).
