Abstract. Asymptotic formulas for calculating a scattering field of an arbitrarily oriented magnetic and electric dipole located on axis of a perfectly conducting disk were obtained using the method of physical theory of diffraction and the method of uniform asymptotic theory of diffraction. Radiation patterns were calculated using the asymptotic formulas and a numerical solution of a singular integral equation. The obtained results were compared to ones available in literature. A dependence of the front-to-back ratio on the disk’s radius was investigated.

Keywords: perfectly conducting disk, spherical wave, dipole, physical theory of diffraction, uniform asymptotic theory of diffraction.
