According to one embodiment, an antenna apparatus comprises an antenna element connected to a feeding point, a grounded first lumped constant element connected to the antenna element, and a grounded second and third lumped constant elements connected to the antenna element through a selector. The selector is configured to connect the grounded second lumped constant element to the antenna element in order to lower a resonant frequency of the antenna element, and to connect the grounded third lumped constant element to the antenna element in order to raise the resonant frequency of the antenna element.
