In order to realize the ultrawideband suppression of simultaneous switching noise (SSN), a hybrid-embedded novel electromagnetic band-gap (EBG) structure is proposed. The presented EBG structure is based on the traditional Z-bridge EBG embedded the L-bridge EBG structure. By the HFSS software simulation and real test, the results show that the proposed EBG structure can obtain ultrawideband suppression of SSN. Compared with the traditional Z-bridge and L-bridge, the suppression effect is greatly improved. This paper analyzes the reason that the new structure can achieve ultrawideband suppression of SSN based on the equivalent circuit model of the structure. Moreover, the proposed structure will lead to signal integrity problems, which is analyzed by eye diagrams.
