Abstract
A measuring system and a measuring method of an antenna pattern based on near field to far field transformation (NFTF) are provided. The measuring system includes a probe antenna, a reference antenna, and a control system. The probe antenna measures an electric field radiated by an antenna under test to obtain electric field information. The reference antenna measures the electric field to obtain a reference phase. The control system is coupled to the antenna under test, the probe antenna, and the reference antenna, wherein the control system applies near field focusing to the reference antenna to configure a focus point of the reference antenna on the antenna under test, and the control system performs the NFTF according to the electric field information and the reference phase to output far field patterns.
