The invention discloses a coupling structure of a dual-mode medium resonator and a metal resonator. The coupling structure comprises a metal cavity, a metal wall dividing the metal cavity into a dual-mode medium resonant cavity and a metal resonant cavity, a dual-mode medium resonant rod and a metal resonant rod. The metal wall is provided with a through hole. The through hole is internally provided with a metal coupling wire sleeved by a supporting body. One end of the metal coupling wire in the metal resonant cavity is fixedly connected with a coupling disk, and one end in the dual-mode medium resonant cavity is connected with the middle part of a metal coupling rod fixed on the bottom part of the dual-mode medium resonant cavity. A coupling tuning screw is fixed on a covering plate right above the metal coupling rod. The coupling structure is simple in machining technology, low in cost, convenient for mass production and convenient to assemble and debug.
Description
technical field [0001] The invention relates to a passive antenna feeder device in the field of wireless network communication, in particular to a coupling structure of a dual-mode dielectric resonator and a metal resonator. Background technique [0002] For a long time, the filter has been playing an extremely important role in the processing of electronic signals, it is mainly used to filter the signal of the frequency used and suppress the interference signal. With the rapid development of microwave wireless communication and the shortage of frequency band resources, higher and higher requirements are placed on the performance and volume of filters. Traditional filters composed of metal cavity resonators and single-mode dielectric resonators are no longer able to To meet these requirements, it is desired to use dual-mode dielectric resonators to improve the performance of the filter while reducing its size. [0003] In order to save costs and improve the quality factor v...
