A meander line antenna formed by folding a conductive pattern of a folded dipole antenna in the shape of meander is disclosed. The basic structure of the meander line antenna includes a bottom half section formed by a folded conductive pattern, and a feeding point arranged approximately at the center of the folded conductive pattern for mounting an IC chip, a top half section consisting of a folded conductive pattern shaped like the bottom half section, a coarse tuning section consisting of two or more short circuit conductive patterns for coarse tuning that connects countering conductive patterns of either or both of the bottom half section and the top half section at a predetermined interval, and a fine-tuning section consisting of two or more short circuit conductive patterns for fine tuning that connect countering conductive patterns of the top half section, the countering conductive patterns being located at a position that counters the feeding point, at a predetermined interval.
