Title:
TRANSMISSION LINE AND TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/119943
Kind Code:
A1
Abstract:
Provided in the present invention are a transmission line and a terminal device, the transmission line comprising at least one layer of a first ground conductor and a substrate layer; the substrate layer is provided with a signal transmission line and a second ground conductor arranged between the first ground conductor and the signal transmission line, the width of the second ground conductor being greater than the width of the signal transmission line but less than the width of the first ground conductor; the first ground conductor is provided with at least two connection areas and at least one grid area sandwiched between the two connection areas, and the second ground conductor is opposite to the grid area. Arranging the second ground conductor between the grid area and the signal line optimises impedance without changing the structure of the signal line, effectively ensuring the transmission performance of the transmission line.
