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.
