Description

CROSS-REFERENCE TO RELATED APPLICATION This application claims priority to and the benefit of Korean Patent Application No. 10-2023-0141476, filed on Oct. 20, 2023, the disclosure of which is incorporated herein by reference in its entirety. BACKGROUND 1. Field of the Invention The present invention relates to a communication line and a communication system, and more particularly, to a communication line for signal transmission and a communication system using the same. 2. Discussion of Related Art Communication lines made of dielectrics have a lower manufacturing cost than conductor-based communication lines and their installation and management are easier than optical-based communication lines, thereby efficiently utilizing the communication lines in chip-to-chip communications. However, in addition to data signals, various signals may be required to be transmitted using communication lines. There is a problem in that conventional communication lines are not suitable for transmitting various signals and have severe mutual interference between the signals, which causes the quality of the signals to be degraded. Further, conventional communication lines have a problem in that an amount of the outside leakage of signals propagating in the conventional communication lines is excessive. Accordingly, the signals propagating through the conventional communication lines become incomplete, and as the length of the communication line increases, the attenuation of the signal may increase, cumulative signal loss may increase, and noise may be generated in electronic devices around the communication line. Meanwhile, the related art described above is technical information that the inventor possessed for deriving the present invention or acquired during the process of deriving the present invention, and cannot necessarily be considered as publicly known technology disclosed to the general public prior to the application of the present invention.
