Claims14
A superconductive device comprising:
- a dielectric substrate;
- a resonator pattern disposed on a first surface of the dielectric substrate, the resonator pattern having a disk shape, the resonator pattern comprising a superconductive material;
- an input signal line and an output signal line, each of the signal lines being disposed adjacent to the resonator pattern;
- and
- a ground film disposed on a second surface of the dielectric substrate, the ground film comprising the superconductive material,
- wherein the ground film includes an opening pattern, the opening pattern being provided in a region corresponding to a region between a first imaginary line extending from the input signal line over the resonator pattern and a second imaginary line extending from the output signal line over the resonator pattern.
