<p>PROBLEM TO BE SOLVED: To provide an antenna device capable of forming an electric field having sufficient uniformity and strength in a near-field.SOLUTION: The antenna device includes: a first dielectric layer; a ground plane; a conductive line that includes one end to be a feeding point and another end to be a ground end or an open end connected to the ground plane and is disposed on a second surface of the first dielectric layer; a second dielectric layer that is disposed while overlapping the first dielectric layer in the state where the conductive line is held between the first dielectric layer and the second dielectric layer; and a first conductive element and a second conductive element which are disposed so as to cross the conductive line in a planar view at a first position and a second position corresponding to first and second nodes of a standing wave of a current to flow in the conductive line. The first and second conductive elements are curved or bent towards the feeding point in a planar view with respect to the first and second positions crossing the conductive line in the planar view and a curving degree, a bending degree or a length is different for the first conductive element and the second conductive element.</p> |
