Embodiment 1
[0015] Embodiment 1: as Figure 1a , Figure 1b and figure 2 As shown, the hexagonal resonant cavity substrate integrated waveguide filter, the filter includes a dielectric substrate 1 and the upper surface metal copper 21 and the lower surface metal copper 22 respectively located on the upper surface and the lower surface of the dielectric substrate 1; The through holes of the metallization 3 penetrate the dielectric substrate 1 and conduction with the metal copper 21 on the upper surface and the metal copper 22 on the lower surface, and the array of the metallization 3 forms a regular hexagonal first hexagonal resonant cavity connected in sequence 51. The second hexagonal resonant cavity 52 and the third hexagonal resonant cavity 53; Axis 8 is mirror symmetrical but not adjacent; the upper right side of the first hexagonal resonant cavity 51 coincides with the lower left side of the second hexagonal resonant cavity 52 and is provided with a first inductive coupling window ...
