The signal integrity(SI)of high-speed interconnects on meshed ground/power reference plane in high-speed multilayer PCB is investigated both by measurement and simulation.The analysis is mainly based on experimental measurement which incorporated 3D full-wave EM and circuit and system simulation in frequency and time domain.The frequency characteristics of band-pass(band-stop)is theoretically analyzed which caused by the periodic structure of the meshed ground plane.The results are shown that the transmission characteristics of signal lines across the meshes are largely affected by the meshes on the reference plane.Even the band-stop can appear in the frequency ranges of the transmission signal in part

which can degrade the quality of high-speed signal.Finally

the design rules for high-speed interconnects on the meshed ground plane are derived from the results obtained.
