RÉSUMÉ

The amplitude and phase characteristics of electromagnetic radiation of symmetrical thin wire resonant antennas in the near field and intermediate regions have been analyzed. Computer-aided analysis allowed us to establish that the length of the reactive near field depends on the dipole length and has its minimal value in resonance. The radiation pattern of a half-wave dipole is formed at the distances exceeding one-and-a-half wavelength.
