Abstract :
This paper presents three related planar EBG (electromagnetic bandgap) structures based on embedded capacitors and inductors, which have small-footprints and can be used in package power or ground planes to provide wideband isolation among different parts of the power distribution network (PDN). Measurement shows -40dB isolation from 2-2.5GHz to over 10GHz. In order to improve performance at lower frequencies we explore the synthesis of planar EBG structures and Chip Ceramic Capacitors or Ferrite Beads.
