Abstract
An antenna device includes a flat base body and a flat conductive body which is disposed on the base body and which has a polygonal shape such that a lower side opposed to a ground is shorter than an upper side. The conductive body includes a feeding point on the lower side and a slit which comprises an open end on the lower side in a vicinity of the feeding point. The slit includes a first slit portion which extends from the open end, a second slit portion which extends from an end of the first slit portion such that the second slit portion is turned to a perpendicular direction with respect to the first slit portion, and a third slit portion which extends from an end of the second slit portion such that the third slit portion is turned to a perpendicular direction with respect to the second slit portion.
