Abstract :
A mode-matching technique combined with a spectral domain representation is used to study the transmission properties of microstrip lines with a periodically corrugated ground plane. The field components in the corrugated region are expanded by standing wave mode functions in the propagation direction and by a Fourier integral in the transversal direction. Integral equations are formed in terms of the surface currents on the microstrip. The dispersion relation is obtained by applying the method of moments to solve the integral equations. Various geometrical and electrical parameters affecting the passband/stopband characteristics of the first stopband are investigated
