A novel design of power/ground plane with planar electromagnetic bandgap (EBG) structures for suppressing simultaneous switching noise (SSN) is presented. The novel design is based on using meander lines to increase the effective inductance of EBG patches. A super cell EBG structure, comprising two different topologies on the same board, is proposed to extend the lower edge of the band. Both novel designs proposed here are validated experimentally. A -28dB suppression bandwidth starting at 250MHz and extending to 12GHz and beyond is achieved
