There is a wide class of antennas that can be presented as a set of thin-wire perfect conductors. Current distribution, radiation and scattering problems are usually solved by the method of integral equations (IE). While using antennas, there is the possibility of the formation of different kinds of coating, for instance, ice, that can be approximated by an ideal dielectric. In that case, a model of a system of dielectric-coated thin-wire conductors is used. Numerical analysis of an integral equation based on Pocklington's equation for dielectric-coated thin-wire conductors is given. To obtain solution stability, recommendations are offered for choosing a segment length depending on dielectric layer permittivity and thickness.
