Abstract:
1. A method of adjusting filter characteristic of a superconductive filter comprising: a base substrate made of dielectric material; a resonator pattern made of superconductive material and formed over a first surface of the base substrate; an adjustment substrate made of dielectric material and disposed facing the first surface at a distance from the first surface; a package configured to accommodate the base substrate and the adjustment substrate; and a support shaft of dielectric material having a dielectric constant lower than a dielectric constant of the dielectric material of the adjustment substrate, the support shaft being fixed to a surface of the adjustment substrate opposite to a surface facing the base substrate, and at least one end of the support shaft protruding from the package via a through hole disposed in a wall of the package, wherein the method comprises: changing an attitude of the adjustment substrate with reference to the first surface of the base substrate, and wherein the changing the attitude of the adjustment substrate changes an angle between the first surface and a surface of the adjustment substrate facing the base substrate.
