Abstract
There is provided an antenna element capable of implementing miniaturization, acquisition of a high gain, and broadening of a band and coping with multiple bands. The antenna element includes a first antenna elementhaving shape of a box (a rectangular-parallelepiped shape) in which a first conductor plate, a second conductor plate, and a third conductor plateare arranged so as to define at least three surfaces of a substantial rectangular parallelepiped and in which electric power is fed from a substantial corner of a lower circuit board (a ground plate)to the first conductor plate; and a second antenna elementhaving shape of a box (a rectangular-parallelepiped shape) in which a fourth conductor plate, a fifth conductor plate, and a sixth conductor plateare arranged so as to define at least three surfaces of a substantial rectangular parallelepiped, the fourth conductor platebeing connected by way of a resonance circuitto the first antenna elementat a portion thereof apart from a feeding point of the first antenna element
