Abstract:
1. A meander line antenna formed by folding a conductive pattern of a folded dipole antenna in the shape of a meander, having a basic structure comprising: a bottom half section consisting of a folded conductive pattern, and a feeding point arranged approximately at the center of the folded conductive pattern; a top half section consisting of a folded conductive pattern shaped like the bottom half section; a coarse tuning section consisting of a plurality of short circuit conductive patterns for coarse tuning that connect 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 a plurality of 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.
