    摘要: Disclosed herein are an electromagnetic bandgap structure and a printed circuit board having the same. The bandgap structure includes a conductive layer including a plurality of conductive plates, a first metal layer disposed under the conductive layer and including a first stitching pattern electrically connected to a first conductive plate of the plurality of conductive plates, and a second metal layer disposed under the first metal layer and including a second stitching pattern electrically connected to both the first stitching pattern and a second conductive plate of the plurality of conductive plates. The bandgap to structure includes stitching patterns formed in two layers different from the conductive layer, thus offering a stop-band having a desired bandwidth in a compact structure.
