The wave transmission characteristics of rectangular, double-ridge, trapezoidal-ridge and anti-trapezoidal ridge waveguides are analyzed using the finite-element method. The cut-off wavelength and attenuation of these waveguides are calculated. The result shows that anti-trapezoidal ridge waveguides perform better than rectangular, double-ridge and trapezoidal-ridge waveguides. The variation of bandwidth and attenuation with respect to change in the angle of physical ridge structures has been studied while migrating from rectangular to anti-trapezoidal ridge structures.
