Abstract

A novel uniplanar compact electromagnetic band-gap (EBG) structure is proposed for ultrawideband (UWB) suppression of ground bounce noise (GBN) in multilayer PCB. The power plane integrates the features of L-shaped bridges and slits (LBS), which can suppress the GBN at lower and higher frequencies, respectively, without using hybrid periods cascading structures. The GBN suppression bandwidth is broadened from 432 MHz to 15 GHz covering almost the whole noise band for UWB applications. A locally embedded LBS-EBG structure in power plane is proposed to improve signal integrity (SI). Full-wave simulation and measurement are performed to verify the high performance.
