[0020] Example
[0021] In this embodiment, the materials of the first dielectric substrate 2 and the second dielectric substrate 4 of the multilayer hexagonal substrate integrated waveguide filter are Ferro-A6M ceramic substrates, and the relative dielectric constant ε r =5.9, the loss tangent is 0.0015, and the thickness of the single layer after sintering is 0.096mm. Each dielectric substrate is composed of four layers of ceramic substrates. The material of the first metal layer 1, the second metal layer 3, and the third metal layer 5 is gold or silver, and the thickness is 8-12um. The through hole filling material is gold or silver , The diameter of the through hole is 0.17~0.22mm, and the hole spacing is 0.45~0.65mm. The specific structure size of the multilayer hexagonal substrate integrated waveguide filter is marked as figure 2 , image 3 As shown, the specific corresponding parameters are shown in the following table:
