[0003] The general line dielectric waveguide filter is composed of several ceramic resonators. There are blind holes on the ceramic resonators. The deeper the depth of the blind holes, the greater the capacitive coupling strength between adjacent ceramic resonators. The existing 5G Ceramic dielectric waveguide filters for base stations often have the following disadvantages: 1. The thickness of the metal coating at the bottom of the polished blind hole affects the capacitive coupling strength between adjacent ceramic resonators in existing dielectric waveguide filters. Adjustment, the operation method is complicated, and the cost is high; 2. The existing ceramic resonator has an integrated structure, which is not conducive to maintenance and replacement, and the cost is high
