Abstract
An antenna device includes circuitry configured to determine a first distance between a marker center and a fisheye lens, based on a first elevation angle and a coordinate of a marker along a third axis, determine second distances between the fisheye lens, and first endpoints and second endpoints, and control phase adjustment amounts by which phase shifters adjust phases of power transmission signals in a first axis direction and a second axis direction. The circuitry is configured to set phase adjustment amounts for three antenna elements including antenna elements at both ends in the first axis direction and for three antenna elements including antenna elements at both ends in the second axis direction, based on path differences between the first distance and the second distances, and set phase adjustment amounts for a plurality of antenna elements arranged two-dimensionally by parabolic interpolation of a quadratic function.
