Abstract

PURPOSE:To make the size of the titled filter small and to simplify the manufacture by adopting dielectric waveguide structure for a main waveguide. CONSTITUTION:The titled filter consists of a microwave main waveguide 13 whose one end is an input terminal 11 and whose other end is an output terminal 12, a cut-off waveguide 14 existing at least in the lengthwise direction of the main waveguide 13 and connected to its one side, and a resonator member 15 provided in the cut-off waveguide 14 and coupled with the main waveguide 13 via the cut-off waveguide 14. In introducing the cut-off waveguide 14 as above, the limit of size having been a bottle neck to a conventional filter so far to obtain a desired notch characteristic is relaxed. Thus, a small sized notch filter is obtained and the degree of freedom of the design for each part is improved.
