Abstract

The embodiment of the invention discloses a signal transmission line and a terminal device and relates to the technical field of communications, so as to solve the problem that the flat FPC transmission line of an LCP material cannot be turned on due to the breakage of a via hole, thereby causing the signal to be unable to be transmitted. The signal transmission line comprises at least one signalline and a dielectric layer, wherein each of the signal lines comprises a first portion and second portion at both ends; the first portion is a portion on the signal line between the two second portions except the two second portions, wherein the first portion is arranged in the dielectric layer; and each of the second portions is arranged on the first surface of the dielectric layer. The signal transmission line and the terminal device in the invention can be applied to the scenes of signal transmission.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, and in particular, to a signal transmission line and a terminal device. Background technique [0002] In order to reduce transmission loss, radio frequency signals in terminal equipment are generally transmitted using signal transmission lines. With the development of communication technology, for example, the fifth-generation mobile communication technology (Fifth-generation, referred to as 5G) era is coming, due to the increase in the number of antennas, the demand for internal signal transmission lines of terminal equipment increases, and due to the overall The traditional circular coaxial transmission line is no longer suitable as the signal transmission line inside the terminal equipment. [0003] At present, in the prior art, a flat flexible printed circuit (FPC) transmission line made of liquid crystal polymer (LCP) is usually used to replace the traditiona...
