Differential Signal Via Shield with Narrow Via Pitch Partial Electromagnetic Bandgap Structure
This paper presents a signal via shielding method in a printed circuit board with the narrow via pitch partial electromagnetic bandgap (NVP-PEBG) structure. The NVP-PEBG structure was developed to shield a small area such as a signal via with wideband isolation and compact size. This NVP-PEBG structure showed excellent noise isolation for a single-ended signal via. In this paper, the NVP-PEBG structure is applied to a differential signal via and its performance with the differential signal via is demonstrated in coupling against the noise in a power and ground plane.
