Document Type and Number:
WIPO Patent Application WO/2020/003628
Kind Code:
A1
Abstract:
This wireless power feeding device (100) is provided with: an array antenna (3); a storage unit (15) for previously storing information indicating the position or direction of an object 1 to be power-fed; an environmental information input unit (13) for receiving environmental information within a predetermined area (A); a detection unit (11) for detecting, on the basis of the input environmental information, the presence or absence of and the position of an object (50) within the predetermined area (A); and a directionality control unit (10) for controlling, on the basis of the detection result by the detection unit (11), the directionality of the array antenna (3) so that the intensity of radio waves radiated toward the detected object (50) becomes weaker in comparison with the case in which power is transmitted through the radio waves to the object (1) to be power-fed.
