Abstract According to the physical mechanism of the Electromagnetic Band-Gap (EBG) structure and the equivalent circuit model of the planar EBG structure, a novel compact EBG structure is proposed for Simultaneous Switching Noise (SSN) suppression in high speed circuits. -30 dB stop-band is from 0.6 GHz to 6.4 GHz, and the bandwidth is 5.8 GHz. Comparing with the traditional L-bridge EBG structure, the bandwidth increases by 1.8 GHz and the relative bandwidth increases by 45%. A low band-gap center frequency and wide bandwidth is realized and good signal integrity is achieved.
