A wave filter of the kind having at least two dielectric resonators (1a, 2a) in juxtaposition, each resonator having a tubular dielectric body (3a, 3b) on which there are formed an inner conductor (4a, 4b), an outer conductor (5a, 5b) and various other conductors including a resonator coupling conductor (7a, 7b). The outer conductors and resonator coupling conductors on both dielectric bodies are soldered or otherwise coupled together both mechanically and electrically. The confronting side surfaces (13a, 13b) of the dielectric bodies (3a, 3b) have formed thereon nonconductor regions (17a, 17b) of a larger area than heretofore, such that the dielectric resonators are inductively, in addition to capacitively, coupled together. |
