【 摘 要 】

References(13)A novel wideband uniplanar electromagnetic bandgap structure with curved line bridges (C-EBG) is proposed to be used in power planes for suppressed ground bounce noise (GBN) and improved signal integrity. Compared with a conventional uniplanar electromagnetic bandgap structure with straight line bridges (S-EBG), the C-EBG structure significantly increases the equivalent inductance with less splitting in the power plane. The effectiveness of the proposed C-EBG structure was validated both numerically and experimentally. The improvement in bandwidth, GBN suppression, and signal integrity was 70%, 70%, and 20%, respectively.
