PROBLEM TO BE SOLVED: To achieve strong coupling between resonance rods and enable easy adjustment work.SOLUTION: A band pass filter including resonance rods comprises: an external conductor formed by a housing having a cavity therein and formed into a square shape; multiple resonance rods, each of which is disposed in the external conductor so that one end part is grounded on one surface of the exterior conductor and the other end part is open in the external conductor; multiple adjustment screws that are removably inserted into a surface of the external conductor which faces the one surface of the external conductor, are disposed corresponding to the respective multiple resonance rods, and adjust resonance frequencies; and a coupling rod connecting the adjacent resonance rods of the multiple resonance rods with each other. |
