Title:
TRANSMISSION LINE AND TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/119942
Kind Code:
A1
Abstract:
Provided is a transmission line. The transmission line comprises at least one layer of a grounding conductor and a signal layer. A signal transmission line is provided in the signal layer. The width of the grounding conductor is greater than that of the signal transmission line. The transmission line comprises, in a signal transmission direction, at least two connection areas and at least one bending area sandwiched between the two connection areas. In the bending area, the grounding conductor comprises a grounding piece corresponding to the signal transmission line and grounding grids arranged on the two sides of the grounding piece in a direction perpendicular to the signal transmission direction. The grounding piece and the grounding grids are all connected to the grounding conductors in the connection areas at the two ends thereof. According to the transmission line and the terminal device provided in the present invention, a mesh structure is provided in the bending area of the grounding conductor, such that the transmission line is easy to bend during arrangement; and in the bending area, the grounding piece is arranged at the projection position of the signal transmission line on the grounding conductor, thereby reducing the impact of the mesh structure on the impedance, and ensuring the transmission performance of the transmission line.
