Electromagnetic interference noise reduction board using electromagnetic bandgap structure
First Claim
1. An electromagnetic interference (EMI) noise reduction board having an electromagnetic bandgap structure for shielding a noise, comprising:
- a first area having a ground layer and a power layer; and
a second area placed in a side portion of the first area and having an electromagnetic bandgap structure therein so as to shield an EMI noise radiated to the outside through the side portion of the first area,wherein the electromagnetic bandgap structure comprises;
a plurality of first conductive plates and a plurality of second conductive plates placed on a same planar surface along the side portion of the first area; and
a stitching via configured to electrically connect the first conductive plates and the second conductive plates through a planar surface that is different from the first conductive plates and the second conductive plates.
