Title:
ANTENNA DEVICE, POWER SUPPLY DEVICE, AND POWER SUPPLY METHOD
Document Type and Number:
WIPO Patent Application WO/2024/053417
Kind Code:
A1
Abstract:
Provided is an antenna device capable of easily calculating phase adjustment amounts of power transmission signals in a plurality of antenna elements of an array antenna in accordance with the position of a power reception antenna, in order to increase received power. This antenna device: acquires a projection elevation angle; determines, on the basis of the coordinates of first both end points and second both end points in a marker image and a focal distance of a fisheye lens, second elevation angles of the first both end points and the second both end points with respect to a third axis; determines a first distance between the marker center point and the fisheye lens; determines second distances between the fisheye lens and the first both end points and between the fisheye lens and the second both end points on the basis of the second elevation angles of the first both end points and the second both end points with respect to the third axis and third axial coordinates thereof; sets phase adjustment amounts for three antenna elements in each of a first axial direction and a second axial direction on the basis of the route differences between the first distance and the second distances; and sets phase adjustment amounts for a plurality of antenna elements arranged in a two-dimensional manner using parabolic interpolation of a quadratic function.
