The results of investigations into nonlinear effects arising in the simplest radiating and scattering antennas are presented. It is shown that the uneven distribution of nonlinearity surface impedance (NSI) of the antenna or inclusion in the antenna quasi non-linear elements can significantly affect its performance. Varying the absolute values and the shape of the distribution of the NSI can change the shape of the current distribution on the antenna surface, and thus, change the shape of the radiation pattern. This concerns both the basic operating frequency of the antenna, and its higher harmonics. The type of the antenna excitation source is also important. The antenna characteristics on the harmonic frequencies depend on it to a significant extent.
