Abstract
The dual-band antenna device includes: a feeding electrode that branches into a first branch feeding electrode that serves as a low-frequency signal path and a second branch feeding electrode that serves as a high-frequency signal path; and a radiation electrode having a rectangular shape with a longitudinal direction and having a low-frequency feeding point to which the first branch feeding electrode is electrically connected and a high-frequency feeding point to which the second branch feeding electrode is electrically connected. In the radiation electrode, the low-frequency feeding point or the high-frequency feeding point is formed close to an end portion of the rectangular shape in the longitudinal direction, and the high-frequency feeding point or the low-frequency feeding point is formed at a center portion of a side of the rectangular shape that extends in the longitudinal direction.
