An inter-substrate communication device, comprising:
- a first substrate and a second substrate which are disposed to oppose each other with a spacing in between;
- a first resonance section including a first resonator and a second resonator which are electromagnetically coupled to each other, the first resonator being provided in a first region of the first substrate and having an open end, and the second resonator being provided in a region of the second substrate corresponding to the first region and having an open end;
- a second resonance section disposed side-by-side relative to the first resonance section, and electromagnetically coupled to the first resonance section to perform a signal transmission between the first and second resonance sections, the second resonance section including a third resonator and a fourth resonator which are electromagnetically coupled to each other, the third resonator being provided in a second region of the first substrate and having an open end, and the fourth resonator being provided in a region of the second substrate corresponding to the second region and having an open end;
- a first shielding electrode and a second shielding electrode, the first shielding electrode being disposed between the first resonator and the second substrate and partially covering the first resonator to allow at least the open end of the first resonator to be covered therewith, and the second shielding electrode being disposed between the second resonator and the first substrate and partially covering the second resonator to allow at least the open end of the second resonator to be covered therewith;
- a third shielding electrode and a fourth shielding electrode, the third shielding electrode being provided between the third resonator and the second substrate and partially covering the third resonator to allow at least the open end of the third resonator to be covered therewith, and the fourth shielding electrode being provided between the fourth resonator and the first substrate and partially covering the fourth resonator to allow at least the open end of the fourth resonator to be covered therewith;
- a first signal-lead electrode provided in the first substrate, the first signal-lead electrode being physically and directly connected to the first resonator, or being electromagnetically coupled to the first resonance section while providing a spacing between the first signal-lead electrode and the first resonance section;
- and
- a second signal-lead electrode provided in the second substrate, the second signal-lead electrode being physically and directly connected to the fourth resonator, or being electromagnetically coupled to the second resonance section while providing a spacing between the second signal-lead electrode and the second resonance section,
- wherein the signal transmission is performed between the first substrate and the second substrate.
