In this paper, the mathematical model of arbitrarily configurated thin wire antennas with a nonlinear surface impedance (NSI) is offered. The dependence of the current distribution along a monopole antenna on a fundamental frequency and harmonics is presented. The influence of both the "nonlinearity factor" value, and a kind of external excitation source of a dipole, on this dependence and radiator current/time characteristics is shown.
