技術說明

本發明之主要目的係提供一種差模信號線結構，該差模信號線結構之目的在於抑制共模雜訊，並同時能夠應用於多對且緊密靠近的差模傳輸線上。 一種能夠抑制共模雜訊之差模信號線結構，係用以設置於基板，其中基板係由上至下具有互相呈實質平行之信號層、濾波層與接地層，差模信號線結構係包含差模信號線組、第一導線與第一接地電路；差模信號線組係設置於信號層，第一導線係設置於濾波層位於差模信號線組之正下方處，第一接地電路係設置於接地層，並利用第一貫穿孔電性連結於第一導線之端點。 A differential signal line structure is provided according to the present invention, which is to reduce the common mode noise and also to be utilized in differential transmission lines arranged in multi-pairs that are located closely together. The differential signal line structure is disposed on a substrate including a signal layer, a filter layer and a grounding layer, the filter layer and the grounding layer are arranged from up to down and in parallel. The differential signal line structure accordingly includes a differential signal line group, a first wire and a first grounding circuit; the differential signal line group is disposed in the signal layer; and the first wire is disposed in the filter layer and is arranged in a corresponding position right underneath the differential signal line group.
