Abstract

As a new kind of broadband microwave component, transmission characteristics of the dominant TE mode in inverted trapezoidal-ridge waveguide have been analyzed by finite element method. Variations of the cutoff wavelength, single-mode bandwidth, field patterns, characteristic impedance, attenuation constant and power-handling capacity with the varied ridge dimensions have been investigated in details. The longer cutoff wavelength, broader single mode bandwidth and lower characteristic impedance can be achieved for smaller ridge gap. While the lower attenuation and higher power-handling capacity can be realized for larger ridge gap. Numerical results in this paper provide an extension to the existing design data for ridge waveguide and are considered helpful in microwave and millimeter-wave applications.
