Approach for the analysis and Q–factor estimates of patch antennas with artificial dielectrics substrates for decimeter and larger wavelengths have been considered. Parameters range not leading to significant normal dispersion have been estimated and treated. Also shown that a frame of periodic system of capacitive elements aligned along the patch wedges provides smaller Q compared to the homogeneous dielectric substrate with the same equivalent permittivity. Implementation samples for the high accurate positioning with the help of the Global Navigation Satellite Systems are shown.
