Abstract
An electromagnetic bandgap structure is disclosed. In accordance with an embodiment of the present invention, the electromagnetic bandgap structure can include a dielectric layer, a plurality of conductive plates, placed on a planar surface which is different from that of the dielectric layer, vias, of which each is connected to each of the conductive plates, respectively, and penetrates through the dielectric layer from one end part that is connected to the conductive plates, and a conductive trace, which connects the other end parts of the vias with each other such that all of the conductive plates are electrically connected.
