Abstract
A high-frequency transmission device includes first and second resonators as ring-shaped wires each having an opening part at a part thereof, first and second input/output terminals each electrically connected to both resonators, a first ground shield formed on a plane different from planes on which both resonators are arranged, a second ground shield formed on a plane different from the planes on which both resonators and the first ground shield are arranged, and first and second ground wires each formed to surround peripheries of both resonators. The ground shields and the ground wires are respectively connected to each other. A dielectric wire is present between both ground wires, and the ground wires are not electrically connected to each other.

17. A high-frequency transmission device comprising a substrate, an electromagnetic resonant coupler, a transmission circuit, and a receiver circuit, wherein
the electromagnetic resonant coupler includes a first resonant wire arranged on the substrate and electrically connected to the transmission circuit, and a second resonant wire electrically connected to the receiver circuit and arranged on the substrate to oppose the first resonant wire, the transmission circuit includes a high-frequency signal generation unit that is arranged on the substrate and that generates a high-frequency signal, the transmission circuit is arranged on the substrate, generates a high-frequency transmission signal by modulating an input signal by the high-frequency signal generated by the high-frequency signal generating unit, and sends the generated high-frequency transmission signal to the first resonant wire, the first resonant wire transmits the high-frequency transmission signal sent from the transmission circuit, to the second resonant wire, the receiver circuit rectifies the high-frequency transmission signal transmitted to the second resonant wire, generates an output signal corresponding to the input signal, and the receiver circuit is arranged on a main surface of the substrate.
