Abstract
A bandstop filter contains one or more resonant circuits connected by interconnecting transmission lines. The resonant circuits each have a transmission line connected between two capacitors. One capacitor is connected to the interconnecting transmission line and the other capacitor is connected to ground. The resonant circuits may have a helical coil of superconducting materials as the transmission line. The capacitors may be in the form of screws, which can be inserted into or removed from the center of the helix. The helix may be formed as a discrete structure and supported by a low-loss material within a housing.
