Ultra-wideband suppression of ground bounce noise using novel uniplanar compact electromagnetic bandgap structures

In this paper, a novel uniplanar compact EBG structure which integrates L-bridged EBG structure with slits is proposed for ultra-wideband GBN suppression in PCBs. The GBN suppression bandwidth is broadened to cover from 432 MHz to 15 GHz without using multilayer and cascading different period structures. The distinctive behavior of the new EBG power plane in ultra-wideband suppression of the GBN is validated by simulations and measurements.
