Claim:
1. A dielectric resonator comprising a dielectric resonant column, a metal cavity, a sealing cover plate and a tuning screw, wherein the dielectric resonant column is located in the metal cavity, the sealing cover plate is located on an upper end face of the metal cavity, and the tuning screw is located on the sealing cover plate, and the dielectric resonator further comprises multiple insulating fixed modules located between a lower end face of the sealing cover plate and an upper end face of the dielectric resonant column, the lower end face of the sealing cover plate presses above each of the insulating fixed modules and the upper end face of the dielectric resonant column supports each of the insulating fixed modules, a pressure is formed between the sealing cover plate and the dielectric resonant column, so that the dielectric resonant column is fixed at a bottom of the metal cavity.
