Patent ID: 8823216

Claim:
A signal transmission device comprising: a first and a second substrates disposed facing each other in a first direction with a space therebetween; a first resonator including a plurality of first open-ended resonators and a single or a plurality of second open-ended resonators, the plurality of first open-ended resonators being formed in a first region of the first substrate and being electromagnetically coupled to each other in the first direction, the single or the plurality of second open-ended resonators being formed in a region of the second substrate corresponding to the first region, and the plurality of second open-ended resonators being electromagnetically coupled to each other in the first direction; and a second resonator electromagnetically coupled to the first resonator, the second resonator performing signal transmission between the first resonator and the second resonator through the electromagnetic coupling therebetween, wherein the plurality of first open-ended resonators include a first first-open-ended resonator and a second first-open-ended resonator, open ends of the first first-open-ended resonator facing a central portion of the second first-open-ended resonator, a central portion of the first first-open-ended resonator facing open ends of the second first-open-ended resonator, when the plurality of second open-ended resonators are employed, the plurality of second open-ended resonators include a first second-open-ended resonator and a second second-open-ended resonator, open ends of the first second-open-ended resonator facing a central portion of the second second-open-ended resonator, a central portion of the first second-open-ended resonator facing open ends of the second second-open-ended resonator, and the first open-ended resonator and the second open-ended resonator in closest proximity to each other in the first resonator are arranged such that the respective open ends thereof face each other and the respective central portions thereof face each other.
