Abstract
A signal transmission medium for transmitting EHF band signals from a first point to a second point, including: a first end at which a signal exchange with the first point takes place; a second end at which a signal exchange with the second point takes place; and a transmission line portion which is flexible and connects the first end and the second end. The transmission line portion includes: strip conductors which are formed substantially down a center of a flexible printed circuit board to establish electrical connection between a signal line at the first end and a signal line at the second end; and a pair of grounding sheets which are arranged in parallel to each other at a substantially constant gap from the flexible printed circuit board in 180-degree opposite directions. The cavities are formed between the pair of grounding sheets and the strip conductors.
