Abstract

The embodiment of the invention provides a transmission line and electronic equipment, and the transmission line comprises a first dielectric layer, at least one second dielectric layer and a second signal line, the first dielectric layer is provided with a first signal line and ground planes, the ground planes are arranged at the two sides of the first signal line, and the second dielectric layer is provided with a second signal line. The first dielectric layer and the second dielectric layer are flexible dielectric layers, an air layer is arranged between the first dielectric layer and the second dielectric layer, the first signal line is used for transmitting radio frequency signals, the second signal line is used for transmitting digital signals, the radio frequency signals and the digital signals can be transmitted at the same time, and the air layer is arranged between the second signal line and the first dielectric layer. The stress generated by mutual extrusion between the first dielectric layer and the second dielectric layer is reduced, bending of the transmission line is facilitated, the second signal line can take the grounding surface on the first dielectric layer as a reference ground, the grounding surface does not need to be arranged on the second dielectric layer, and the bending performance of the transmission line can be improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of signal transmission, and in particular, to a transmission line and an electronic device. Background technique [0002] As the main carrier of wireless communication, antennas are widely used in various smart devices, such as 5G and sub-6G Mino (multiple-in multipleout) antennas. ”, “portable” appearance and shape, among which, thin and portable folding devices are more and more popular among consumers, and Mino antennas like 5G and sub-6G are multi-antenna systems, and the antennas are not foldable, in order to avoid Multiple same frequency or similar frequencies interfere with each other and adapt to the space of the folding device. The designer usually arranges multiple antennas on the planes on both sides of the folding device, and uses flexible transmission lines in the middle folding area to perform radio frequency between the antennas. Signal transmission. [0003] In the...
