Radio communicating device, rotational structure, and electronic device

摘要

Disclosed herein is a radio communicating device including: a first communicating block; a second communicating block rotatable about an axis of rotation relative to the first communicating block; and a radio signal transmission line capable of information transmission by radio between the first communicating block and the second communicating block; wherein between the first communicating block and the second communicating block, a signal to be transmitted is converted into a radio signal of a circularly polarized wave, and the radio signal of the circularly polarized wave is transmitted via the radio signal transmission line.
