Signal transmission line and user terminal equipment

Abstract

The embodiment of the invention relates to the technical field of communication, and discloses a signal transmission line and user terminal equipment. The signal transmission line is used for transmitting signals between a main board and an antenna board; the signal transmission line comprises a torsion section extending along a first direction and connecting sections extending outwards from two tail ends of the torsion section respectively; the tail end of one of the connecting sections is used for being electrically connected with the main board, the tail end of the other connecting section is used for being electrically connected with the antenna board; the torsion section and each connecting section each comprise LCP dielectric layers and signal layers which are alternately stacked; the torsion section is provided with M LCP dielectric layers and M + 1 signal layers; each connecting section is provided with N LCP dielectric layers and N + 1 signal layers; M is smaller than N, and N is larger than N, and M and N are integers greater than 0. According to the signal transmission line and the user terminal equipment provided by the embodiment of the invention, the condition that the rotation effect of the millimeter wave antenna of the user terminal equipment is limited due to the adoption of a connecting line which is easy to wind can be avoided, so that the communication quality of the user terminal equipment will not be influenced.

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 and user terminal equipment. Background technique [0002] CPE (Customer Premise Equipment, user terminal equipment) equipment is a user terminal equipment for wireless broadband access. CPE equipment usually transmits wireless network signals sent by base stations, such as 4G (4th Generation Mobile Communication Technology, fourth generation mobile communication technology) signals , 5G (5th Generation Mobile Communication Technology, fifth-generation mobile communication technology) signal, converted to WiFi (wireless communication technology) signal, the user only needs to insert the CPE device into the SIM (Subscriber Identity Module, user identity module) card, and turn on the power That's it. CPE equipment can effectively save the cost of laying wired networks (such as optical cables, copper wires). Therefore,...

Problems solved by technology

However, when the millimeter-wave antenna board is mechanically rotating, the main board (including the 5G signal processing part) is fixed on the inner frame of the CPE device, and the CPE device does not need to be rotated, the connection line connecting the millimeter-wave antenna to the signal processing part of the main board is prone to failure. Wrapping or even breaking, resulting in the limitation of the rotation effect of the millimeter wave antenna, which in turn affects the communication quality of the user terminal equipment
