Abstract
According to one embodiment, an antenna includes first and second coupling elements and first to fourth connecting elements. An electrical length between a middle point of the first coupling element and each of both open ends thereof is a first electrical length which is an odd multiple of ¼ of a wavelength λ corresponding to a frequency used for close proximity wireless communication. An electrical length between a middle point of the second coupling element and each of both open ends thereof is the first electrical length. An electrical length of each of the first to fourth connecting elements is a second electrical length which is an odd multiple of ¼ of the wavelength λ.
