摘要
文中应用电磁场解析方法并结合传输线理论计算了同轴线、平行偏心同轴线、斜偏心同轴线特性阻抗,进而对偏心同轴线等效为无偏心同轴线时的等效长度以及偏心后引起谐振频率的变化作了计算,解决了介质同轴谐振腔加工过程中由于工艺不完善引起的中心孔偏差所带来的问题。
This paper deals with the problem of the centre hole deviation of the dielectric coaxial resonators used in the newly dielectric antenna duplexer.This problem is caused by the technological imperfections in manufacturing.The solution to the characteristic impedance of the off-centre coaxial transmission lines,the equivalent length and the prequence devia- tion of the off-centre dielectric resonator is obtained by using an analytical method of elec- tromagnetic field.This could provide an important basis for the modification of every pa- rameter and limit the extent of the error.
