PROBLEM TO BE SOLVED: To simplify layout of assembled parts regardless of whether or not input and output side connectors are provided. SOLUTION: This is coaxial type dielectric filter is configured with a cutoff waveguide 1, two coaxial dielectric resonators 21,22 placed almost coaxially in the cutoff waveguide 1 at a distance, an input side rod antenna 32 whose tip is inserted into an input side inner conductor layer of the coaxial dielectric resonator 21 placed at the input side, and an output side rod antenna 42 whose tip is inserted into an output side inner conductor layer of the coaxial dielectric resonator 22 placed at the output side. In this case, while each coupling amount (1/Ex) between the antennas 32,42 and the coaxial dielectric resonators 21,22 is adjusted in advance to satisfy a prescribed coupling condition, the antennas 32,42 and the coaxial dielectric resonators 21, 22 are fixed and integrated, before they are assembled in the cutoff waveguide 1. |
