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.

Based on the solution of the boundary value problem for an infinite antenna array, a mathematical model of a finite flat antenna array in an infinite screen with impedance structure is built. Results of calculations are given by the example of radiant strips.
