Abstract :
A novel concept for ultra-wideband suppression of switching noise in high-speed printed circuit boards (PCBs) is proposed, implemented and tested. This concept consists of using non-symmetrical, embedded electromagnetic bandgap (EEBG) structures in conjunction with material with high dielectric constants. The proposed design modifies the classical EEBG structures to achieve a high degree of miniaturisation and an unprecedented broadband suppression of switching noise.
