A mathematically accurate method of analysis of a spherical-disk antenna conformally printed on a dielectric-covered metallic sphere is presented. The antenna is fed by a radial coaxial probe simulated by an electric dipole. The solution consists of reducing the boundary-value problem to the dual-series equations, and further to a regularized infinite-matrix equation. This procedure is based on the analytical inversion of the static part of the problem of a disk in free space, and results in a stable and fast algorithm with a guaranteed convergence. Numerical data on the basic antenna characteristics are presented.
