Abstract: In an electronic switching beamforming antenna array, a coplanar feeding line of the antenna array is configured on a metal plane of a substrate, and a plurality of slot antennas of aforementioned antenna array are inclinedly configured on the metal plane and configured on at least one side of the coplanar feeding line. A slot coupling segment of slot antenna is configured at one end of the slot antenna and neighbored with the coplanar feeding line so as to make the slot antenna couple with the coplanar feeding line, and a switch device of the slot antenna is configured at one portion which between one part of the slot antenna and a grounding plane formed by the metal plane. When the switch device is triggered to configure a radiating feature of the slot antenna, the antenna array is able to achieve the purpose of setting beamforming direction.

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.
