Ka波段紧凑型TE01-TE11椭圆波导模式转换器的研究
Research on the compact TE01-TE11 elliptical waveguide mode converter in Ka-band
摘要
Abstract
In this article,the elliptic waveguide TE01-TE11 mode converter is studied.The proper elliptical wave-guide cross section is selected,the phase re-matching method is used in the elliptical waveguide longitudinal con-tour line function,and the longitudinal contour line optimization is performed using a particle swarm algorithm,and the designed elliptical TE01-TEs11 mode converter has a conversion efficiency of 99.16%at 28 GHz.The effi-ciency of the mode converter at 27-29.3 GHz is more than 90%,and the relative bandwidth is 8.2%.The conver-sion section of the designed TE01-TEs11 elliptic mode converter is half of the existing length.The designed ellipti-cal 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 TE01-TE11 mode converter with a center frequency point of 28 GHz is designed.关键词
