Abstract:
1. An electromagnetic bandgap structure comprising: a metal layer; a dielectric layer, stacked on the metal layer; a plurality of metal plates arranged two-dimensionally on a same planar surface of the dielectric layer; and a plurality of stitching vias configured to electrically connect the adjacent metal plates with one another, wherein the stitching via comprise a first via, an end part of which is connected to any one of two adjacent metal plates; a second via, an end part of which is connected to the other of the two adjacent metal plates; and a connection line pattern, placed on a same planar surface of the metal layer, an end part thereof being connected to the other end part of the first via, the other end part thereof being connected to the other end part of the second via, wherein metal plates that are not placed in outermost areas of the two-dimensionally arranged metal plates are respectively connected with at least three of the stitching vias.
