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.
