Abstract :
A spiral-shaped electromagnetic bandgap (EBG) structure is proposed to suppress simultaneous switching noise effectively when the power plane drives high-speed ICs. The new EBG structure is locally or periodically utilised on the power plane. Even with reduced unit cell size, its port-to-port transmission characteristic shows a much wider stopband than other conventional EBG structures.
