摘要
基于门钮窗结构设计适合高功率微波传输的同轴TEM模——矩形TE10模的微反射过渡结构,经优化后,此类过渡结构在L波段驻波比小于1.1的相对带宽超过4%。在同轴线中增加感性销钉后,此类微反射过渡结构可以与另一段同轴线构成多节带通滤波器。研究表明:感性销钉取向对过渡结构的通带有重要影响,只有沿平行于矩形波导方向插入销钉才能得到最宽的通带。
A doorknob type little reflection transition of coaxial TEM mode to rectangular TE10 mode for high power microwave transmission is designed and discussed. The relative bandwidth, of which the stand wave ratio is smaller than 1.1, is bigger than 4%. In order to make the transition couple with another stage of coaxial line to form a multi-stage filter to broaden pass band, an inductive metal pin should be added in the coaxial line. The research shows that the direction of the metal pin has a great effect on t...
