The invention relates to a high frequency filter of coaxial construction, comprising an outer conductor housing with a housing base and a housing wall, whereby several resonators are embodied in the outer conductor housing, each comprising an inner conductor tube, electrically-coupled to the housing base. At least one part of adjacent resonators are electrically-coupled to each other by means of at least one coupling opening in the outer conductor housing. Said filter is characterized in that one or more recesses are embodied in the housing base, between at least one part of the inner conductor tube of adjacent resonators. |
