Claims

[Scope of utility model registration request]

a dielectric substrate, a main line formed on the dielectric substrate by a microstrip line, an input side circuit connected to the main line input side, an output side circuit connected to the main line output side, and the above-mentioned A sub-line formed by a microstrip line provided in parallel with the main line, a varactor diode connected to the tip of the sub-line, and a dielectric resonator provided between the main line and the sub-line. In the variable band-stop filter, the dielectric substrate is divided between a main line and a sub-line, and a slide mechanism for moving the dielectric substrate on the sub-line side parallel to the main line;
A variable band-stop filter comprising: a shim for adjusting the height of the dielectric substrate on the sub line side with respect to the dielectric substrate on the main line side.
