Title:
RADIO WAVE CONTROL SYSTEM, CONTROL DEVICE, RADIO WAVE CONTROL METHOD, AND NON-TRANSITORY COMPUTER READABLE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/181118
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a radio wave control system that can perform beam forming for a plurality of signals having different frequencies. The radio wave control system of the present disclosure comprises: a high power amplifier (10) for generating a broadband local signal including a first local signal of a first frequency and a second local signal of a second frequency; a reflective plate (20) for modulating the first local signal and the second local signal when the first local signal and the second local signal are reflected or passed through by periodically arranged antenna elements (22), and forming first modulated signal and second modulated signal into beams in respectively different directions; and a control device (30) for electrically controlling the antenna elements (22) to control the phases of the first local signal and the second local signal incident to the reflective plate (20), thereby controlling the directions toward which beams for the first modulated signal and the second modulated signal are formed.
