摘　　要：经理论分析得出,一段小曲率半径弯曲圆波导的传输特性和一段与其弯角相同、轴线长度相等的斜接弯波导的传输特性一致,从而提出了一种由多节直圆波导依次倾斜连接构成的TM01-TE11斜接弯波导模式转换器,并介绍了该模式转换器的设计方法,给出了设计实例。优化结果表明,所设计的模式转换器在中心频率上均具有99%以上的转换效率。Analysis of bend waveguides shows that a small curvature-radius bend waveguide and a mitered-joint waveguide that have equal bend angles and equivalent axial lengths have similar transmission characteristics.Therefore,a new kind of TM01-TE11 mode converter,which is composed of several mitered-joint straight waveguides,are proposed and studied.Design method of such converters is studied,and several sample are presented,all of which have high conversion efficiencies of greater than 99% at center frequency.
