Embodiment Construction

[0042]Objects, some specific advantages and novel features of the present invention will become more apparent from the following detailed description and examples in connection with the accompanying drawings. It should be noted that, in this specification, when reference numerals are attached to components in each drawing, the same components are given the same numbers as much as possible even if they are shown in different drawings. Further, terms such as first and second may be used to describe various constituent elements, but these constituent elements should not be limited by these terms. These terms are only used for the purpose of distinguishing one element from another. In addition, in describing the present invention, when it is judged that the detailed description of the related art may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted.

[0043] Embodiments of the present invention will be described in detail b...

Abstract

The invention relates to a flexible circuit board. The flexible printed circuit of the present invention is characterized in that the first substrate portion including the first signal line and the second substrate portion including the second signal line parallel to the first signal line are disposed on the same plane with the shield portion interposed therebetween. .

Description

technical field [0001] The present invention relates to a flexible circuit board. Background technique [0002] Wireless terminals such as mobile phones, tablet computers, and notebook computers are equipped with RF (Radio Frequency, radio frequency) signal lines. Conventional RF signal lines are installed in the form of coaxial cables. When installed in the form of coaxial cables, the space in the wireless terminal equipment is utilized. The performance has decreased, so flexible circuit boards are commonly used these days. [0003] On the other hand, in wireless terminals, recently, with the development of communication technology, two or more RF signal lines are used for transmission of short-range communication signals such as WIFI and / or wireless mobile communication signals such as 3G and 4G. [0004] As described above, in the case of RF signal lines, if a coaxial cable is used in order to prevent mutual signal interference, etc., the space occupied in the wireless t...
