With the development of modern communication technology and market demand,rubidium atomic clocks are constantly updated and are developing towards miniaturization and high performance.As the core component of rubidium atomic clock,microwave resonator is naturally developing towards miniaturization.The working principle of rubidium atomic clock and the resonance theory of microwave resonant cavity are described,the common resonance modes and field distribution of rubidium atomic clock are analyzed,and the development and mode transition of rubidium atomic clock microwave resonant cavity are introduced.On this basis,a standard TE_(111)resonant cavity filled with ceramic dielectric and a non-standard resonant cavity with a mode similar to TE_(011)are developed.The rubidium atomic clock microwave resonator will continue to develop towards smaller size and higher performance in future.
