Abstract
In this article, a novel electromagnetic bandgap structure is applied to a high-speed printed circuit board, where the proposed concept is to etch with traditional L-bridge and extended connecting branches on the power plane. To investigate the electromagnetic characteristics of the proposed structure, its transmission performance is determined including an equivalent circuit to numerically predict the lower cutoff frequency. A near field electromagnetic interference measurement is carried out compared to a reference board to investigate the simultaneous switching noise suppression ability.
