Title:
ANTENNA DEVICE, POWER SUPPLY SYSTEM, POWER SUPPLY APPARATUS AND POWER SUPPLY METHOD
Document Type and Number:
Japanese Patent JP2022191880
Kind Code:
A
Abstract:
To provide an antenna device which can suppress the spread of reflection of a signal that has been transmitted and reduce the influence of interference to another device that may exist in the periphery.SOLUTION: In a power supply apparatus 100, an antenna device 100A comprises: an array antenna 110; a phase shifter 120 which adjusts the phase of a power transmission signal supplied to a plurality of antenna elements 111; a camera 140 which acquires an image; and a control device 150. The control device 150 comprises: a position derivation unit which converts the position of the image into polar coordinates; an elevation angle acquisition unit which acquires an elevation angle of the image; a memory which stores plural sets of plural pieces of phase data according to the plurality of elevation angles; and a control unit which controls the phase shifter 120 that adjusts the direction of the beam emitted by the array antenna on the basis of the phase data.SELECTED DRAWING: Figure 1
