Abstract
A superconducting microstrip filter capable of achieving an improvement of power resistance without enlarging the overall size and while maintaining steep cut characteristics. This filter has a resonator section including at least one resonator. This resonator forms a current density reduction part in one part of its line pattern. Also, the filter has an input line section arranged adjoining the resonator of an initial stage. Current density reduction parts are formed in one part of this input line section. Alternatively, the input line section is comprised of a normal conductor.
