Abstract

This paper discusses reduction of radiated emission of a printed circuit board by implementing Electromagnetic Band Gap structures (EBG) in the power distribution system. EBG structures and their effect on power plane resonances is analysed and several boards with EBG structures have been designed. The performance of standard power plane and EBG structured power plane has been measured. The scattering parameters show a reduction in resonances and the absorbing clamp measurements demonstrate a reduction in common mode currents and therefore radiated emission, indicating the feasibility of radiated emission reduction by means of EBG structured power planes.
