PROBLEM TO BE SOLVED: To provide an antenna device which can form an electric field having enough uniformity and strength in a near-field.SOLUTION: An antenna device includes: a ground plane disposed on a first surface of a rectangular first dielectric layer in a planar view; a conductive wire which has one end to be a feeding point, a ground terminal grounded on the ground plane, or another end to be an open end, and is disposed on a second plane of the first dielectric layer; a second dielectric layer which is disposed on the second plane of the first dielectric layer with the conductive wire between itself and the first dielectric layer; a plurality of first conductive elements which are disposed in the way that they cross the conductive wire in a planar view at a plurality of first positions corresponding to nodes of standing wave of current on the second plane opposite to the first plane layered on the first dielectric layer of the second dielectric layer; and one or a plurality of second conductive elements which are disposed in the way that they cross the conductive wire in a planar view at one or a plurality of second positions corresponding to antinodes of the standing waves of current between the first positions nearest another end of the plurality of first positions and the other end on the second plane of the second dielectric layer. |
