摘　　要：为了确保抑制高速电路中同步开关噪声(SSN)的微波光子晶体(EBG)结构在兼顾带隙特性的同时,还具有良好的信号完整性,采用枝条绕转单元贴片的方法设计出一种新型EBG结构。利用HFSS软件对新型EBG结构抑制SSN的特性进行建模仿真,并制备刻蚀有新型EBG结构的4层印制电路板,用安捷伦矢量网络分析仪对其禁带特性进行测试,实验结果与仿真结果吻合良好。通过眼图对新型EBG结构进行的仿真分析显示,新结构的信号完整性良好。Electromagnetic bandgap （EBG） structure to inhibit the simultaneous switching noise （SSN） in high-speed circuit needs not only qualified bandgap properties, but also good signal in- tegrity. Based on previous research results on microwave photonic crystal EBG structures, a new EBG structure is proposed to optimize the design and simulate its inhibition SSN characteristics by HFSS software. The new EBG structure with a 4-layer etching printed circuit board（PCB） are also prepared, and its inhibition characteristics are tested. Experimental results and simulation results are in good agreement. Eye diagram is used to analyze the signal integrity of the new EBG structure. Simulation results show that the new structure has good signal integrity.
