System and method for measuring antenna radiation pattern in fresnel region based on phi-variation method

Abstract

Provided is a system and method for measuring an antenna radiation pattern in a Fresnel region based on a phi-variation method. The system includes a rotator for changing angles of a reference antenna and a target antenna; a vector network analyzer for obtaining radiation pattern data in accordance with transmission/reception radio frequency (RF) signals between the reference antenna and the target antenna; a measurement unit for calculating a far-field radiation pattern based on the radiation pattern data received from the vector network analyzer; and a controller for controlling the rotator according to a measurement angle transmitted from the measurement unit.

Dependencies are inferred from the claim text.
