<p><P>PROBLEM TO BE SOLVED: To provide an electromagnetic bandgap structure for shielding the noise of a specific frequency band. <P>SOLUTION: An electromagnetic bandgap structure includes a plurality of conductive plates located on a first horizontal surface and a stitching via part for electrically connecting two conductive plates for each two conductive plates among a plurality of conductive plates. The stitching via part includes a first via with one end connected to one of the two conductive plates, a second via with one end connected to the other of the two conductive plates, a spiral connection for forming a spiral series connection structure on at least one vertical plane orthogonal to the first horizontal surface, a first conductive connection pattern for connecting one end of the spiral connection and the other end of the first via, and a second conductive connection pattern for connecting the other end of the spiral connection and the other end of the second via. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
