ANTENNA DEVICE AND POWER FEEDING DEVICE

Title:

ANTENNA DEVICE AND POWER FEEDING DEVICE

Document Type and Number:

WIPO Patent Application WO/2020/170508

Kind Code:

A1

Abstract:

Provided are an antenna device with which the direction of a beam can be controlled with a simple calculation; and a power feeding device.　The antenna device includes: an array antenna that has a plurality of antenna elements arranged two-dimensionally along a first axis and a second axis; a phase regulating unit that regulates, in the first axis direction, the phases of power supplied to the plurality of antenna elements; an image acquiring unit that acquires images through a fish-eye lens; a position converting unit that converts a first position with respect to the image acquiring unit for markers included in the images acquired by the image acquiring unit, into a second position in polar coordinates on a first plane that includes the first axis and the second axis; an elevation angle acquiring unit that, on the basis of the second position, derives, with respect to a third axis within a second plane, the elevation angle of a projection position to which the first position is projected onto the second plane that includes the first axis and the third axis; and a control unit that controls the phase regulating unit so that the direction of a beam emitted by the array antenna forms the elevation angle within the second plane.
