Problems solved by technology

[0004] The problem with such a transmission line is that stress builds up on the bent portion during multiple bends, causing damage to the bent portion
[0005] In particular, since the signal line is located in the dielectric of the bent part, there is a problem that when the dielectric is stressed, cracks are generated in the signal line and the high-frequency transmission function of the transmission line is lost.

Embodiment Construction

[0041] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that those skilled in the art of the present invention can easily implement them.

[0042] The present invention can be implemented in many different ways and is not limited to the embodiments described in this specification.

[0043] In a transmission line with a strip structure or a microstrip structure that is divided into bent portions 20 that are repeatedly bent and straightened on the basis of the base portion 10, there are bends in the transmission line that are caused by stress accumulation in the bent portion 20 during multiple bends. 20 damaged issues.

[0044] In particular, since the signal line 100 is located in the first dielectric 210 of the bent portion 20 , when the stress is accumulated on the first dielectric 210 , cracks will occur in the signal line 100 , and thus there is a problem of losing the high-frequency transmission function...

Abstract

The present invention relates to a transmission line having improved bending durability, the transmission line having a strip structure or a microstrip structure divided into a base portion and a bent portion repeatedly bent and straightened with the base portion as a reference, Wherein, the base portion and the curved portion include: a signal line extending in the longitudinal direction in a manner of transmitting a high-frequency signal; a first dielectric, on which the signal line is formed on the upper surface or the lower surface; and a second A dielectric is formed on the upper portion of the first dielectric, and the second dielectric is combined with the first dielectric at the base portion and separated from the first dielectric at the bent portion.

Description

technical field [0001] The present invention relates to a transmission line with enhanced bending durability. Background technique [0002] Wireless communication terminals such as smartphones, tablets, and notebooks include transmission lines for transmitting high-frequency signals to antennas. [0003] Recently, a transmission line is arranged across a hinge inside a foldable wireless communication terminal that can be folded and opened so as to be bent together when the wireless communication terminal is folded and opened. [0004] A problem with such a transmission line is that stress accumulates on the bent portion when it is bent many times, causing the bent portion to be damaged. [0005] In particular, since the signal line is located in the dielectric of the bent portion, there is a problem that when the dielectric is stressed, cracks are generated in the signal line and the high-frequency transmission function of the transmission line is lost.
