Applying the electromagnetic bandgap (EBG) structure to power/ground planes of printed circuit boards (PCBs) helps prevent electromagnetic waves from propagating between them at frequencies of interest. We experimentally demonstrated that interposing noise suppression sheet (NSS) into power bus of PCBs is effective for not only miniaturizing the EBG structure but also expanding the stopband towards higher frequencies. This paper clarifies the mechanism of the phenomenon that appears when applying the NSS to the power bus. To distinguish the effects due to permittivity and permeability of the NSS, the S-parameter measurement with the strong magnetic field applied was carried out. The measurement results showed the stopband shift towards lower frequencies results from the effect of the anisotoropic permittivity of the NSS on the electric field around the slit of the EBG pattern.
The phenomenon was validated by the full-wave simulation by Microwave Studio. Also, an effective approach of applying the NSS to the EBG pattern was experimentally investigated. |
