<p><P>PROBLEM TO BE SOLVED: To provide an electromagnetic band gap structure and a printed circuit board. <P>SOLUTION: A printed circuit board 100 includes three or more conductive plates; a first stitching via 645 for electrically connecting one conductive plate among the conductive plates with another conductive plate; and a second stitching via 649 for electrically connecting the one conductive plate among the conductive plates with yet another conductive plate. In the first stitching via, a part thereof electrically connects the one conductive plate with another conductive plate via one upper flat plane of one conductive plate, and in the second stitching via part thereof electrically connects the one conductive plate is electrically connected to yet another conductive plate via one lower flat plane of one conductive plate. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
