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 ...

It is shown that the method is based on reducting the source vector problem to two scalar problems for Debye potentials. The amplifying ration and directional diagrams of antennas based on spherical dielectric lenses are researched and experimental estimation of numerical results is given.

Tags: antenna , spherical , dielectric , lens , Debye Path: Home / Publications / Archives A numerical algorithm for solving the problem of diffraction of electromagnetic waves on a multilayer dielectric lossy sphere when amplitudephase distribution of the exciting field is arbitrary is developed. The algorithm is based on representing the field on the source surface as an aggregate of the electrical and magnetic dipoles and reducting the vector problem to two scalar ones for the case of a point source. The results of calculating the directional diagrams and amplifying ratio are compared...
