Beschreibung
Zusammenfassung:	A dielectric filter comprising a plurality of lambda /4 coaxial-type dielectric resonators connected in series, each having a dielectric between internal and external conductors, wherein at least one resonator whose external conductor is grounded through a capacitance or inductance is included. The dielectric filter of the present invention is embodied as a low-pass filter, high-pass filter, or band-pass filter. Thus, a dielectric filter having a peak attenuation in the vicinity of the pass band and producing only a small insertion loss can easily be obtained by using dielectric resonators having a desired resonance frequency.
