三角形对称双脊波导的有限元分析与设计
Analysis and design of triangular symmetric double ridged waveguide by finite element method
摘要
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 bandwidth, field pattern, characteristic impedance, attenuation constant and power-handling capacity on the varied ridge dimensions have been investigated in details. Compared with the conventional rectangular ridged waveguide, TSDRW provides 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.关键词
