Abstract

The embodiment of the invention discloses a signal transmission line and a manufacturing method thereof. The terminal device relates to the technical field of communication, in order to solve the problem that a flat FPC transmission line made of LCP material can not be transmitted due to a conduction hole being broken, thereby causing the signal to be unable to be transmitted. The signal transmission line comprises: the signal transmission line has a cross-sectional shape of any shape other than a circular shape, The signal transmission line comprises at least one signal line layer, each signal line layer comprising a dielectric, and a core wrapped by the dielectric and M first ground planes, the core and any one of the M first ground planes not in contact, wherein M is an integer greaterthan or equal to 2. The signal transmission line can be applied to scenarios of signal transmission.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular to a signal transmission line, a manufacturing method thereof, 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 usual...
