<p>A dielectric filter (1A) which functions as a band elimination filter for attenuating only a signal of a particular frequency region, and includes a dielectric block (2) formed with a plurality of through-bores (3) in it in a parallel relation to each other, inner-conductor layers (4) respectively formed within the through-bores, an outer-conductor layer (5) formed at least on an outer side face (2b) of the dielectric block, so as to constitute a plurality of resonators (7), coupling members (9) respectively disposed within the through-bores for capacitive coupling with the inner conductor layers, and a concentrated constant line (10) respectively connecting neighboring ones of the coupling members.</p> |
