RÉSUMÉ

The system of non-linear integral equations describing the current distribution in the wire radiators with non-linear surface impedance is obtained. Using the moment method the given system is reduced to a harmonic balance equation system. It is shown by the example of the wire vibrator analysis, that at the stage of approximation of the unknown current distribution in linear and non-linear parts of the integral operator it is possible to use different systems of basic functions, and at the stage of transformation of initial integral equation to the harmonic balance equation it is possible to use different systems of weight functions.
