SIGNAL TRANSMISSION MEDIUM AND HIGH FREQUENCY SIGNAL TRANSMISSION MEDIUM

WIPO Patent Application WO/2012/073785

A1

[Problem] To provide a signal transmission medium with flexibility capable of transmitting high frequency signals. [Solution] This signal transmission medium transmits a signal of EHF band from a first point to a second point and includes: a first edge portion for transmitting and receiving the signal to and from the first point; a second edge portion for transmitting and receiving the signal to and from the second point; and an elastic transmission path portion (10) for connecting the first edge portion and the second edge portion. The transmission path portion (10) includes: a strip conductor (11) formed at a substantially center portion of a ribbon-like flexible printed board (13) for realizing conduction between signal lines of the first edge portion and the second edge portion; and a pair of grounding sheets (12) arranged in parallel at substantially equivalent intervals in the direction 180 degrees different with respect to the flexible printed board (13). The pair of grounding sheets (12) is partially supported by a flexible spacer (14) made of an insulating member respectively, and a cavity (15) is formed between each grounding sheet (12) and the strip conductor (11).
