Vertical Cascaded Planar Ebg Structure for SSN Suppression

Abstract

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.

Patch antenna with multi-cell EBG for RF energy harvesting applications

“…It can be observed that using MEBG, the gain of the antenna at one particular frequency is improved whereas enhancing gain at multiple frequencies is difficult. To address this drawback of MEBG, cascading of EBGs has been proposed in [9][10][11]. EBGs can be modeled as LC parallel resonator circuit, so cascading of EBGs is similar to that of cascading bandstop filters.…”

“…EBGs can be modeled as LC parallel resonator circuit, so cascading of EBGs is similar to that of cascading bandstop filters. As discussed in [9][10][11], by changing either patch width or vias radius or periodicity of MEBG, cascaded EBGs can be obtained.…”

Embedding Electromagnetic Band Gap Structures in Printed Circuit Boards for Electromagnetic Interference Reduction

“…All the patches have the same resonant frequency. In order to increase the bandwidth of EBG cascading two or more EBG structures with different unit cell periods that have different stopbands was proposed [63,64]- [65]. The drawback of these designs is the cost and manufacturing complexity because several power/ground plane areas are occupied Frequency, [GHz] general EBG example to cascade different stop-band EBG.…”
