PROBLEM TO BE SOLVED: To provide a resonator which is equipped with an input/output mechanism of an antenna system, which facilitates positioning of an antenna, and which dispenses with a screw for adjusting the degree of coupling. SOLUTION: A resonator, which is equipped with an input/output mechanism of an antenna system, propagates a high-frequency signal, and constitutes a filter device by being combined with a resonator in which only a resonance rod is disposed. The resonator comprises a coupling rod which is connected to a terminal for inputting or outputting the high-frequency signal and which is disposed in parallel with the resonance rod via an insulator in a cabinet, and a coupling line which is made of a metallic conductor, which has one end connected to the terminal and which has the other end fixedly connected to the coupling rod by means of a screw made of an insulator. The coupling rod is disposed via the insulator in the cabinet by means of the screw to function as an antenna, and electromagnetically coupled to the resonance rod. COPYRIGHT: (C)2012,JPO&INPIT |
