Multi Band noise mitigation in PWR/GND plane pairs by using a 2D EBG structure with square patches and meander lines

Abstract

In this paper a two dimensional (2D) electromagnetic Bandgap (EBG) structure is proposed for multi band noise mitigation in PWR/GND plane pairs. Excellent noise suppression (-60dB) is achieved in multiple bands within the range 0-8GHz with a low start frequency. Because of the 2D EBG, no additional metal layer is required. Signal Integrity analysis is also studied by modelling a microstrip to stripline transition and by evaluating insertion loss, TDR as well as eye diagram.
