摘　　要：根据电磁波理论,对复合绝缘介质同轴结构的传输性能进行了分析,提出了复合绝缘介质同轴结构特性阻抗的共面补偿方法,推导了关键参数的计算公式,设计了3种模型;然后利用高频结构软件对设计模型的电压驻波比进行了模拟计算,并进行了对比分析,讨论了复合绝缘介质同轴结构设计中几个关键参数对电压驻波比的影响。模拟结果表明,提出的共面补偿方法适用于复合绝缘介质同轴结构的特性阻抗补偿,可以降低电压驻波比,从而提高同轴结构的传输性能。The transmission performance of coaxial structures with composite dielectrics is discussed based on the electromagnetic wave transmission theory. The method for coplanar impedance compensation is proposed and the key parameters of coaxial structures with composite dielectrics are calculated. Several coaxial structures with different insulation dielectrics are designed using the method, and their transmission performance is simulated by high frequency structure software. The results show that the method is applicable to the design of coaxial structure, and is helpful to reduce the voltage standing wave ratio, thus improve the transmission performance of coaxial structures.
