Abstract
An electromagnetic bandgap structure and a printed circuit board having the same are disclosed. In accordance with an embodiment of the present invention, the electromagnetic bandgap structure can include a plurality of conductive layers, placed between two conductive layers; and a stitching via, configured to make an electrical connection between any two conductive layers of the conductive layers. Here, the stitching via can include a first via, one end part of the first via configured to any one of the two conductive plates; a second via, one end part of the second via configured to the other of the two conductive plates; and a connection pattern, placed on a planar surface that is different from the conductive plates, between the two conductive layers and configured to make an electrical connection between the other end part of the first via and the other end part of the second via. Any one of the first via and the second via can be formed to penetrate a same planar surface as at least one of the two conductive layers.
