“…For example, mushroom-like EBG structure [4] and 3-D cascaded mushroom EBG [10] can be used to reduce SSN, but it leads to the increased cost in print circuit board (PCB). However, the planar EBG structures are suitable for a low-cost design and also adapted to suppress SSN [11][12][13][14], such as L-bridge structure, meander-L structure and π-bridge structure. But the bandwidth of these structures is limited.…”

Abstract-A novel vertical cascaded planar electromagnetic bandgap (EBG) structure is proposed for SSN suppression with the ultrawideband at the restraining depth of −30 dB by analyzing the simultaneous switching noise (SSN) suppression mechanism and the equivalent circuit model for EBG structure. Moreover, the SSN suppression bandwidth can be broadened by using different novel EBG structures required by vertically cascading different planar EBG structures. In addition, the structure is verified to meet signal integrity (SI) by the time-domain simulation. The tested results show that the presented EBG is accordant to the simulated results of the theory method by the vector network analyzer. The proposed structures provide a new designing method for EBG structures to improve the ability of suppressing SSN.

Abstract-This work aims to compare the implementation of two metamaterials for reducing electromagnetic interference (EMI) in printed circuit boards (PCBs).Specifically, complementary split-ring resonators (CSRRs) and electromagnetic bandgaps (EBGs) were etched on the ground plane of a microstrip transmission line. Both techniques were compared as EMI filters, taking into account frequency response, signal integrity, and near-and far-field radiation with regard to a reference (solid ground) board. The results of electromagnetic simulations and experimental tests show similar EMI rejection levels in both cases, butCSRRs have a significantly better signal integrity response whereas EBGs behave as lower electromagnetic radiation elements in the operation frequency band.

“…Therefore, EBG structures for ultra-wideband (UWB) [13] SSN suppression are becoming the mainstream in the research field. The structures proposed by [2,14,15] are etched on both power and ground planes, respectively, which can reduce stop-band center frequency and improve stop-band bandwidth. The shortcoming is that split power and ground planes may destroy the continuity of the planes, which could cause a serious SI problem.…”

According to electromagnetic bandgap (EBG) structure of the simultaneous switching noise (SSN) suppression mechanism and coplanar EBG structure equivalent circuit model, a novel structure of Meander-L Bridge is proposed for SSN suppression in high-speed circuits. Simulation and measurement results show that the stopband ranging from 210 MHz to 20 GHz at −30 dB suppression of the bandgap depth. Furthermore, the suppression bandwidth is more than 19.79 GHz to achieve the ultra-wideband SSN suppression. Moreover, time-domain simulation results show that the structure in high-speed circuits is met with signal integrity.
