It is shown that when the antenna radius is increased, directive gain of spherical antenna with optimal excitation asymptotically approaches directive gain of the equivalent flat cophasal aperture with uniform amplitude–phase distribution of collinear currents. The results of approximate calculations are compared with the received strict solution.
