Abstract

A signal transmission device comprises a high-frequency signal waveguide. The high-frequency signal waveguide is configured to transmit a high-frequency signal emitted from an electronic device. When the electronic device is at least proximate to a flat surface of the high-frequency signal waveguide, the high-frequency signal is directly coupled from the electronic device to the high-frequency signal waveguide and transmitted via the high-frequency signal waveguide.
