Novel two-dimensional EBG is put forward to suppress the simultaneous switching noise of electronic systems, Based on the inductance enhanced by the long-line metal between adjacent unit cell, the novel two-dimensional EBG structure is achieved by the units lattice structure, which is made of the connection of a square metal and two metal serpentine lines. Simulation results show that the stopband bandwidth of new EBG structure labeling on capacitor is 0 ∼ 6GHz (S2≤-25dB)in the same parameters EBG classic.
