摘要 通过数值模拟与理论计算,对TM01-TE11弯形圆波导模式转换器进行了分析,得出了TE11模式的功率转换效率的解析公式.在保持其出射端口与入射端口轴线平行的情况下,通过减小波导内半径,从而减小波导轴线长度,实现了其结构的小型化设计.当转换器的两段轴线曲率半径相等时,理论计算结果与模拟结果相吻合,且功率转换效率高.优化结果为:波导内径为7.0 cm,模式转换器出射端口与入射端口的轴线间距为8.03cm,轴向长度为15.11 cm;频率在3.41～3.74 GHz内,功率转换效率超过90%,其中频率为3.60 GHz时,转化效率为95.6%. The bent TM01-TE11 mode converter is analyzed by theoretical calculation and numerical simulation, keeping the axes of the output port and that of the input in parallel. The mode converter is minimized by decreasing the inner radius of waveguide. The optimized results are shown as follows: the inner diameter of waveguide is 7.0 cm, the distance between the axes of the two ports of the mode converter is 8.03 cm, and the axial length is 15.11 cm. The overall power conversion efficiency exceeds 90% in the frequency range from 3.41 to 3.74 GHz and the efficiency reaches up to 95.6% at 3.60 GHz.
