Design, implementation and testing of miniaturized electromagnetic bandgap structures for broadband switching noise mitigation in high-speed printed circuit boards

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 asymmetrical, 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 miniaturization and an unprecedented broadband mitigation of switching noise.
