Abstract :
Periodically nonuniform coupled microstrip lines are analyzed on the basis of a numerical field calculation. As the case of the single nonuniform microstrip line described in an earlier paper, Floquet´s theorem is used to express all field quantities in terms of their spatial harmonics. The boundary value problem is formulated in a rigorous way and then solved using Galerkin´s method in the Fourier-transform domain. Numerical and experimental results are presented
