摘　　要：提出了一种在信号线上刻蚀电磁带隙(EBG)结构的微带线互连结构及其设计方法.该互连具有良好的通带传输特性和阻带抑制特性,所以能够抑制同步开关噪声(SSN),保证信号的完整性.该EBG微带线互连采用印制电路板(PCB)工艺进行了加工,S参数的仿真与测试结果具有良好的一致性,表明该互连可以有效抑制同步开关噪声.另外,将该EBG微带线互连与在接地板上刻蚀相同尺寸的EBG的微带线互连做了对比,散射参数和时域波形的分析结果表明,提出的EBG微带线互连具有更强的SSN抑制能力和更好的信号完整性.In this paper, a microstrip transmission line interconnection and its design method are proposed based on the electromagnetic bandgap(EBG). It has good passband transmission characteristics and stopband rejection characteristics, so it can suppress simultaneous switching noise(SSN) and keep the signal integrity. The proposed EBG microstrip line interconnection is realized with printed circuit board(PCB) and measured with network analyzer. Simulation and experimental results of the S parameter of the proposed interconnection agree very well. Besides, comparison between the proposed interconnection with EBG etched on the signal line and the microstrip line with EBG structure etched on the ground plane of the same size show that the proposed interconnection has a stronger capability of suppressing SSN and better signal integrity.
