Title:
SIGNAL TRANSMISSION LINE
Document Type and Number:
WIPO Patent Application WO/2021/235263
Kind Code:
A1
Abstract:
This signal transmission line (1) comprises a first substrate (10), a second substrate (21), and a plurality of conductive joining materials (50). The first substrate (10) comprises a signal conductor (111). The second substrate (21) comprises a ground conductor (211). The plurality of conductive joining materials (50) join the first substrate (10) and the second substrate (21) such that there is a space (SP) therebetween. The first substrate (10) comprises a mounted conductor (121) to which each of the plurality of conductive joining materials (50) is joined. The mounted conductor (121) has a section that runs parallel to the signal conductor (111) closer toward a first side surface (SL1) and a section that runs parallel to the signal conductor (111) closer toward a second side surface (SL2). A location, in the section of the mounted conductor (121) toward the first side surface (SL1), to which the conductive joining materials (50) do not connect and a location, in the section of the mounted conductor (121) toward the second side surface (SL2), to which the conductive joining materials (50) do not connect are different in the signal transmission direction.
