Abstract
An electromagnetic band gap device is provided, comprising: a conductive plane; a non-conductive substrate located over the conductive plane; and an electromagnetic band gap unit cell that includes a first via located in the non-conductive substrate and filled with a conductive material, a second via located in the non-conductive substrate and filled with the conductive material, a first conductive surface located on the non-conductive substrate over the first via, and a second conductive surface located on the non-conductive substrate over the second via, wherein the electromagnetic band gap unit cell is configured to operate as an LC resonant circuit in conjunction with the conductive plane, at least one gap is located in the electromagnetic band gap unit cell, the at least one gap being located in the first via, in the first conductive surface, in the second conductive surface, and in the second via.
