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.
