英文摘要：

In this paper, the design and analysis of the cyclotron wave rectifier cavity at 2.85 GHz is proposed; the influence of the coupling loops on S-pramaters of high frequency system are analysed by computer simulation tech-nology （CST）, and the cavity is also optimized on the basis of prior works; the CST PIC is adopted to solve the influences of the electronic injection on characteristics of the resonator. A cyclotron wave rectifier resonator is designed which possess high energy and high conversion efficiency at 2.85 GHz.
