Abstract
According to one embodiment, an antenna device includes a short circuit path, a first open-ended element, a feed side element, a second open-ended element, and a short circuit element. A length, from a ground point to a second end of the first open-ended element through the short circuit path and the first open-ended element, is substantially a quarter of a wavelength of a first resonant frequency. A length, from the ground point to a second end of the second open-ended element through the short circuit path, the short circuit element, and the second open-ended element, is substantially a quarter of a wavelength of a second resonant frequency.
