    摘要: Disclosed herein is an electromagnetic bandgap structure, including: a dielectric layer; a plurality of conductive plates formed on one side of the dielectric layer; a stitching via serving to electrically connect two adjacent conductive plates of the plurality of conductive plates; and a first dummy via formed each of the plurality of conductive plates in a direction of thickness of the dielectric layer, and a printed circuit board comprising the electromagnetic bandgap structure. The printed circuit board comprising the electromagnetic bandgap structure can solve a mixed signal problem even when an analog circuit and a digital circuit are simultaneously mounted therein.

    摘要: Disclosed herein is a printed circuit board. When power layers for supplying different voltages are sequentially stacked, a first EBG cell formed between a first power layer and a ground layer is arranged within a second EBG cell formed between a second power layer and the ground layer to allow the first EBG cell and the second EBG cell to have a double EBG structure. Accordingly, the present invention can prevent a DC open state while preventing noise and realizing band-stop characteristics.

    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.
