Printed circuit board having electromagnetic bandgap structure

摘要

Disclosed is a printed circuit board including an electromagnetic bandgap structure. The electromagnetic bandgap structure for blocking a noise is inserted into the printed circuit board. The electromagnetic bandgap structure can include a first conductive plate; a second conductive plate arranged on a planar surface that is different from that of the first conductive plate; a third conductive plate arranged on a planar surface that is different from that of the second conductive plate; and a stitching via unit configured to connect the first conductive plate and the third conductive plate by bypassing the planar surface on which the second conductive plate is arranged and including a first inductor element.
