PROBLEM TO BE SOLVED: To provide an antenna device including a loop shaped antenna formed by a pattern on a substrate, and to provide a technique of a downsizing method of the antenna device.SOLUTION: In an antenna device, an antenna is mounted on a substrate. The antenna device includes: a ground part formed on the substrate; a feeding point connected with the ground part and supplying electric power to the antenna; and the antenna which has one end serving as a feeding part and connected with the ground part through the feeding point and the other end serving as an earth part, connected with a point near the ground part with which the feeding part is connected, forming a loop shape, and having a portion located adjacent to the ground part and formed into a meander shape. |
