A super wideband X-complementary split ring resonator structure for power distribution network

In this paper, A novel wide-band uniplanar electromagnetic band gap (EBG) structure composed of complimentary split ring resonator (CSRR) and X shape bridge, called the X-CSRR EBG structure, is proposed to suppress ground bounce noise (GBN) and simultaneous switching noise (SSN) in power ground plane. Compared with conventional uniplanar EBG structures, such as the AI-EBG structure and the S-EBG structure, the proposed X-CSRR EBG structure has more noise suppression depth and larger noise suppression bandwidth. The stop-band of the proposed structure can span from 520MHz to 30GHz with -30dB noise suppression standard. Both the simulation and measured results are represented to verify the noise suppression performance of the proposed X-CSRR EBG structure.
