A physically small antenna having a wide bandwidth that facilitates the inspection of the attachment to the printed circuit board. The antenna is provided with a dielectric plate having a rear surface, a conductive plate disposed on the rear surface, a vertical element extending in a direction perpendicular to the rear surface. The vertical element includes a dielectric bar, an end of which is attached to the rear surface, and a conductive shell covering a side and an opposite end of the dielectric bar to be attached to the conductive plate.
