    • According to one embodiment, an antenna device according to this embodiment includes first and second feed terminals. The distance between the first and second feed terminals is set to a distance less than or equal to almost one quarter a wavelength corresponding to a predetermined resonant frequency. A first end of the first antenna including a first band, as a communication band, including the resonant frequency is connected to the first feed terminal. A first end of the second antenna including a second band, as a communication band, including at least the resonant frequency of the first antenna is connected to the second feed terminal. A first protruding portion is provided between the first and second antennas so as to protrude from a ground pattern of an antenna board.

    • According to one embodiment, a multiply resonant antenna device according to the embodiment includes a first antenna element formed from a monopole element, a second antenna element formed from a parasitic element placed at a position where it can be current-coupled to the first antenna element, and a third antenna element formed from a folded monopole element. The length of the first antenna element is set to nearly a ¼ of wavelength corresponding to the first resonant frequency. The length of the second antenna element is set to nearly a ¼ of wavelength corresponding to the second resonant frequency. The electrical length of the third antenna element from the feed point to a ground point through a folding end is set to nearly a ½ of wavelength corresponding to the third resonant frequency higher than the first and second resonant frequencies.
