Patent ID: 8508415

Claim:
An antenna for transmitting and receiving an electric wave in two different frequency bands, said antenna comprising: a conductor; a first slot and a second slot formed in the conductor to be facing to each other, an opened end of the first slot and an opened end of the second slot being formed on opposite sides of the conductor, respectively; a boundary conductor provided between the first and second slots; and a feeding point, wherein a length of the second slot from the boundary conductor to the opened end of the second slot is shorter than a length of the first slot from the boundary conductor to the opened end of the first slot, wherein the feeding point is located only at the second slot, and wherein the length of the first slot is set based on a first wavelength of the electric wave in one of the frequency bands, and the length of the second slot is set based on a second wavelength of the electric wave in another one of the frequency bands.
