Abstract: An antenna device comprises: a printed circuit board formed with both sides in a plate shape including a first surface and a second surface and including at least one conductive layer between the first surface and the second surface; an array of conductive plates formed parallel to the first surface on or in the printed circuit board; a wireless communication circuit electrically connected to the array of conductive plates, coupled to the first surface, and capable of transmitting or receiving frequencies between 3 GHz and 300 GHz; and a conductive shielding structure mounted on the first surface of the printed circuit board and electrically connected to the at least one conductive layer when covering the wireless communication circuit, wherein the conductive shielding structure may include: a third surface facing the first surface when seen from the top of the first surface; and an electromagnetic bandgap (EBG) structure formed on the third surface.
