This paper presents an approach to analyze the microstrip lines using Vector Dyadic Green's function. The vector Dyadic spectral Green's function is obtained directly from the Spectral domain immitance approach thus leading to a discretized system of equations which can be utilized in the semi analytical analysis of the planar microwave structures and resonators. Finally, the equations so derived have been used to analyze the characteristics of microstrip line in simple and suspended configurations. The current distribution on the strip is also calculated. The results thus obtained were found to be in good agreement with results using Spectral Domain Approach (SDA). Ill. 5, bibl. 9 (in English; summaries in Lithuanian, English and Russian).
