“…Electromagnetic Bandgap (EBG) structures have considerable effects on suppression of the SSN. The coplanar EBG structures possess good performance in low frequency [2][3][4][5][6][7][8][9][10], but the narrow bandwidth makes it cannot achieve the wideband SSN suppression due to the limitations of its own electrical characteristics. The mushroom EBG structure has been embedded between power and ground planes to mitigate the SSN [11][12][13][14], which increases the bandwidth of the stopband, but it decreases low frequency inhibition performance and increases fabrication cost.…”

In this article, by analyzing the equivalent circuit mode for electromagnetic bandgap (EBG), a novel compact planar EBG structure is proposed for overcoming the drawback of narrow bandwidth of conventional EBG structures. The novel design is based on using meander lines to increase the effective inductance of EBG patches. The simulated and measured results demonstrate the simultaneous switching noise (SSN) can be mitigated with an ultra‐wideband from 280 MHz to 20 GHz at the restraining depth of −40 dB. Compared with the traditional L‐bridge and meander lines EBG structures, this novel structure has the advantages of suppression bandwidth and fabrication cost. Moreover, signal integrity is achieved by the time‐domain simulation. The proposed structure provides a new kind of theoretical designing reference for EBG structure to improve the bandwidth of restraining SSN. © 2013 Wiley Periodicals, Inc.
