Abstract :
The expressions for determination of characteristics of radiation and scattering by symmetrical cruciform electrical dipole are found on the basis of mathematical model of this radiator. The influence of excitation of asymmetrical harmonics of current in other arm of radiator in stimulation of cruciform dipole one arm is considered. The results of numerical research of the current distribution on the dipole arms and the pattern of scattering are considered for various lengths of arms and directions of wave falling.
