Patch antennas with artificial dielectrics substrates



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 ...

Variational methods for problems of wave dispersion



Using the generalized variational principle, the article derives the stationary formulas for metallic body dispersion diagram, with variation going to zero for exact values of surface currents, generated on the body by the primary incident wave. Radio engineering and electronics

About minimizing the integral diameter of dispersion of aperture antennas



The formula that relates the integral diameter of the distance to the effective absorbing surface of the aperture receiving antenna is derived and using this formula, the conditions of minimizing the diameter and its value are found. Radio engineering and electronics
