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. © 2000 John Wiley & Sons, Inc. Microwave Opt Technol Lett 26: 176–182, 2000.
