SIGNAL TRANSMISSION DEVICE, ELECTRONIC DEVICE, AND SIGNAL TRANSMISSION METHOD

摘要

A signal transmission device includes: a transmitting device that transmits a transmission subject signal through a first waveguide as a wireless signal; and a receiving device that receives the wireless signal of the transmission subject signal transmitted from the transmitting device through a second waveguide, wherein the wireless signal is transmitted between the transmitting device and the receiving device in a state where the first waveguide faces the second waveguide.
