Abstract

The application of the regularization task of the radiation field by a screening sphere with the circular aperture is proposed. We examine the radiation field of the vertical electrical dipole from sphere. We solve auxiliary integral equations of Abel's type and select main part of functional equations by introducing the small parameter. We obtain linear algebraic equations of second kind of Fredholm's type. New possibilities of improvement of computational algorithms and different characteristics of spherical antenna are discussed.
