摘要

在对新型三角形对称双脊波导特性参数研究的基础上

应用有限元法系统分析计算了三角形对称双脊波导几何尺寸变化对截止波长、单模带宽、场结构、特性阻抗、衰减常数及功率容量等传输特性的影响。与常规矩形双脊波导相比

三角形对称双脊波导具有小的截止波长、窄的单模带宽、低的功率容量、高的衰减常数和大的特性阻抗

可用于窄带微波滤波器。得到的数据结论将为三角形脊波导在微波系统中的设计应用提供详细的设计数据。

Abstract

The characteristic parameters of novel triangular symmetric double ridged waveguide（TSDRW） have been analyzed and calculated by employing finite element method.Dependence of the cutoff wavelength

single-mode band-width

field pattern

characteristic impedance

attenuation constant and power-handling capacity on the varied ridge di-mensions have been investigated in details.Compared with the conventional rectangular ridged waveguide

TSDRW pro-vides short cutoff wavelength

narrow single-mode bandwidth

low power-handling capacity

high attenuation and large characteristic impedance.The TSDRW structure can be developed as the microwave filter with narrow-band operation.Numerical results provide extensive design data for the application of TSDRW in microwave systems.
