Research and Design of W-Band Waveguide Mode Generator

Abstract

In this paper, the research of W-band TE62 coaxial mode generator is studied in detail, and the purity of the mode is improved by selecting a complex coaxial cavity. In order to improve the ability to suppress the unwanted mode, the optimized three-stage smooth coaxial cavity has been used. based on the method of the surface impedance matching theory, the resonant cavity was designed and optimized using the code writing by MATLAB program. Finally, the commercial electromagnetic simulation software is used for verification. The simulation result shows that the purity of the mode exciter is 96.80resonant frequency is 94.12 GHz.
