Abstract
An electromagnetic bandgap structure is disclosed. In accordance with an embodiment of the present invention, the electromagnetic bandgap structure that blocks a noise of a certain frequency band can include 4 or more conductive plates, a first stitching via, which electrically connects any two of the conductive plates with each other by having a part of the first stitching via pass through a planar surface that is different from a planar surface of the conductive plates, a second stitching via, which electrically connects another two of the conductive plates with each other by having a part of the second stitching via pass through a planar surface that is different from a planar surface of the conductive plates, and a stitching via chain, which electrically connects the first stitching via and the second stitching via with each other.
