The dispersion characteristics of slowing and attenuation of the dominant and first higher mode of a single-strip line on a single dielectric layer are investigated by the Finite Element Method. The numerical solution has been obtained using a resonator model with the line inside it and direct finding of the complex eigenvalues for the cross section. It’s shown that the results of both techniques for the slowing coefficient of the dominant and first higher modes are practically identical, and there is a good conjugation for the attenuation. Cross and longitude components of the electric field of the dominant and first higher modes are presented. The calculated attenuation dependences from the frequencies of dominant modes of a single-strip and a microstrip line are compared.
