Abstract
According to one embodiment, an antenna device includes first and second split ring resonators and a power supply line. The first split ring resonator includes a conductor enclosing a first opening and having a first void separating a part of the conductor. The second split ring resonator is opposed to the first split ring resonator, including a conductor which encloses a second opening and has a second void separating a part of the conductor. The power supply line feeds power to the first or second split ring resonator. The first split ring resonator is not electrically connected to the second split ring resonator. The first void does not overlap with the second void in an opposing direction of the first split ring resonator and the second split ring resonator.
