    摘要: Disclosed are an electromagnetic bandgap structure and a printed circuit board including the same. In accordance with an embodiment of the present invention, the printed circuit board can include a dielectric layer, a plurality of conductive plates, and a stitching via, which is configured to electrically connect the conductive plates to each other. The stitching via can pass through the dielectric layer, and a part of the stitching via can be placed in a planar surface that is different from a planar surface in which the conductive plates are placed. With the present invention, the electromagnetic bandgap structure can prevent a signal of a predetermined frequency band from being transferred.
