“…As shown in Figure , there are three stopbands (the gray areas) in the frequency range from about 0.5 to 0.9 GHz, from 1.1 to 1.35 GHz, and from 1.5 to 1.55 GHz, which means the resonant modes caused by SSN will be suppressed within these stopbands. These stopbands are different from the suppression bandgap of insertion loss, and it is mainly because the suppression band of the insertion loss is extracted for a finite number of EBG structures. Moreover, a bandgap implies the absence of propagating modes, whereas, a suppression band does not imply the absence of propagating modes …”

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.
