Embodiment Construction
[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0032] Please refer to figure 1 , which shows a dual-mode dielectric filter provided by an embodiment of the present invention, the dual-mode dielectric filter includes: an input terminal 1 , a plurality of resonant cavities and an output terminal 6 connected in sequence. Wherein, the input end 1 and the output end 6 are arranged along the axial direction of the dual-mode dielectric filter, thus facilitating the vertical integration of the dual-mode dielectric filter and the antenna element.
[0033] The first and last resonant cavities in the plurality of resonant cavities are single-mode resonant cavities, and the rest of the resonant cavities are dual-mode resonant cavities 4 . figure 1 The first single-mod...
