ABSTRACT:
A filter of the distributed constants type which has a dielectric substrate, a transmission line electrode and at least one branch electrode on the dielectric substrate, the branch electrode being connected to the transmission line electrode. This filter is advantageous because it is capable of easily eliminating or passing various frequency bands by changing the structure of the electrodes on the dielectric substrate. Further, wide band elimination and/or large attenuation can be easily achieved by connecting in series the filters having various electrode structures.
