ABSTRACT:
In a waveguide resonator, either coaxial or noncoaxial, there are inserted spaced slots which establish inductances in series with the waveguide structure at the location of each slot. These slots tune the resonance of the waveguide cavity, which would generally be used in a bandpass filter. Switch means are provided for each slot for discretely altering the value of the inductance established, whereby the resonator or filter may be tuned to a large number of different frequencies.
