Abstract :
In this paper, partially loaded periodic microstrip lines are studied. Floquet´s theorem and spectral domain approach (SDA) are used to formulate coupled integral equations. Method of moments is then applied to convert the coupled integral equations to a matrix equation. Numerical results show that the loading factor of the periodic structures can be used to adjust the bandwidth of the first two stopbands. Leakage in the radiation region is also observed
