In this paper, an efficient method for mitigating simultaneous switching noise (SSN) propagation in high-speed printed circuit boards (PCBs) is proposed, using localized power plane topologies, where complementary split ring resonators (CSRRs) are partially etched on one metallic layer of the embedded capacitance. The equivalent circuit model of the proposed structure is presented to predict the lower cutoff frequency of the transmission behavior. An ultra-wideband suppression of SSN from 0.41 GHz to 15 GHz is achieved with a high mitigation level of -60 dB. The measured S-parameter of the proposed structure agrees well with the simulated one. Furthermore, signal integrity (SI) is investigated and it is found that the proposed structure has a good SI performance, because the partial CSRR structure has less influence on signal transmission along the boards than global discontinuity structure.
