An antenna device (10) includes a meandering radiating conductor plate (11) composed of a metal ribbon having a predetermined width that is folded a plurality of times so as to meander, a capacitive conductor plate (14) disposed substantially parallel to a ground conductor (12) and connected to the top end of the meandering radiating conductor plate, a connection conductor plate (15) for electrically shorting the capacitive conductor plate to the ground conductor, and a straight radiating conductor plate (16) extending upwardly in a vertical direction and being connected to the bottom end of the meandering radiating conductor plate. The antenna device operates as a dual-band antenna where the meandering radiating conductor plate resonates by feeding first high-frequency power and the straight radiating conductor plate resonates by feeding second high-frequency power that has a higher frequency than that of the first high-frequency power. <IMAGE> |
