Abstract:
A disclosed antenna device includes a plate-like ground plate, and a feeding unit that extends from the ground plate for a predetermined length at a predetermined angle. The feeding unit is constituted by a half-body, which is a body, such as a circular cone, halved by a plane perpendicular to the ground plate, and the feeding unit is prepared perpendicular to the ground plate.
