摘　　要：本文对椭圆波导TE_(01)-TE_(11)模式转换器进行了研究。选择了合适的椭圆波导截面,在椭圆波导纵轮廓线函数中采用了相位重匹配方法,并利用粒子群算法进行了纵轮廓线优化,所设计的椭圆TE_(01)-TEs_(11)模式转换器在28 GHz时的转换效率为99.16%,在27~29.3 GHz模式变换器的效率大于90%,相对带宽为8.2%。所设计的TE_(01)-TEs_(11)椭圆模式转换器的转换段为现有长度的一半。将设计的椭圆模式转换器与两个过渡段相连,并在CST中进行仿真和验证,其结果与理论计算一致。设计出了一个中心频率点为28 GHz的高效、紧凑、高功率椭圆波导TE_(01)-TE_(11)模式转换器。In this article,the elliptic waveguide TE_(01)-TE_(11) mode converter is studied.The proper elliptical waveguide cross section is selected,the phase re-matching method is used in the elliptical waveguide longitudinal contour line function,and the longitudinal contour line optimization is performed using a particle swarm algorithm,and the designed elliptical TE_(01)-TEs_(11) mode converter has a conversion efficiency of 99.16%at 28 GHz.The efficiency of the mode converter at 27-29.3 GHz is more than 90%,and the relative bandwidth is 8.2%.The conversion section of the designed TE_(01)-TEs_(11) elliptic mode converter is half of the existing length.The designed elliptical mode converter is connected to two transition segments and simulated and verified in CST,and the results are consistent with the theoretical calculations.An efficient,compact,high-power elliptical waveguide TE_(01)-TE_(11)mode converter with a center frequency point of 28 GHz is designed.
