A novel electromagnetic bandgap (EBG) structure is proposed to suppress the simultaneous switching noise in high‐speed circuits. The proposed EBG pattern is etched on the power plane while the ground plane remains intact. The unit is composed of an S‐bridge EBG embedded with a coplanar EBG. The proposed EBG structure possesses an ultrawide bandgap extending from 0.28 to 25 GHz when the suppression depth is −45 dB. A prototype of the proposed EBG power plane is fabricated and tested, and good agreement is achieved between the simulation and the measurement.
