Abstract:Thisstudyinvestigates theapplicationofEBGstructures in high-speedPCBs forsuppessng SSN.Byanalyzing thegeneration mechanism of SSNandtheprinciplesof EBG,we designedandoptimizedamushroom-shaped EBG structure. SimulationandexperimentalverificationdemonstratethattheoptimizedstructureexhibitsexcellntSSNsuppressionperformance within the 2～5GHz frequency range,，achieving maximum suppression levels exceeding 40 dB.These resultsmeet the noise suppression requirements for high-speed PCBs,providing valuable references forrelated design practices.
