| 摘 要： | 研究了一种新型的枕形波导,该枕形波导一方面考虑到矩形波导管的变形,另一方面又有优于矩形波导的优点,其特性阻抗小,易于和低阻抗同轴线、微带匹配,在传输相同波长电磁波时有较小的波导尺寸.分析了枕形波导的截止特性、带宽特性及主模的阻抗特性.

| Abstract: | A novel pillowy wave-guide is investigated,where the deformation of rectangle wave-guide is taken into consideration and,on the other hand,it has the advantages of little characteristic impedance to match well with low-impedance coaxial line and microstrip,and smaller size to transmit electromagnetic waves with identical wavelenth.The cut-off characteristics,bandwidth characteristis,and characteristic impedance of dominant mode of this pillowy waveguide are analyzed. |

| Keywords: | pillowy wave-guide finite element bandwidth dominant mode |
