- In this paper, we present a method to miniaturize electromagnetic band-gap (EBG) structure. EBG is used to suppress noise occurred as tons of switching devices switch on and off simultaneously. In the proposed model, slits exist on both power and ground planes of power distribution network (PDN), which is called 3-D EBG due to the geometric configuration. The method to miniaturize EBG structure is based on signal return path theorem. Two-layered 3-D EBG structure is fabricated, and 3-D full-wave simulator, HFSS, is used to calculate S21 parameter. The measured and calculated S21 parameter shows high isolation, suppressing the noise under-40dB at the frequency range of 2.8 GHz to 8.3 GHz. Finally the performance of the proposed 3-D EBG structure is compared with the other two 2-D EBG structures and shows its superiority to them. © 2008 IEEE.
