摘要
基于弯曲圆波导耦合理论和规则圆波导突变结构模式匹配法,利用MATLAB软件编写的相关数值计算程序得到波导模式转换结构的优化参量,最终使用CST软件对模型进行了仿真和验证.该系统主要由三部分组成:一个TE_(01)-TE_(01)的过渡器,TE_(01)-TE_(11)和TE_(11)-HE_(11)的圆波导模式转换器.计算结果表明,该TE01-HE11模式转换系统在24.13 GHz的频率有5%的带宽、转换效率超过了99%.计算结果、仿真结果和实物冷测结果是一致的.
Based on the curved circular waveguide coupling theory and regular circular waveguide junction mode matching method, the TE01-HE11 Mode Converter model was designed using the optimization parameter of the waveguide mode conversion structure obtained from relevant numerical calculation program, and was successfully simulated and verified by the CST software. The system is mainly composed of three parts ： a TE01 -TE01 mode tran- sition, two circular waveguide mode converters for TE01-TE11 and TE11 -HE11. The calculations showed that the conversion efficiency of the TE01 -HE11 mode converter system is over 99% within the bandwidth of 5% relative to 24.13 GHz. The results of simulations and test are consistent with that of calculation.
