  Dipole antennas have been invented a hundred years ago. Nevertheless, what
really happens in their proximity during emission (the so-called near-field) is
still an open question and the many explanations put forth are not fully
convincing. Subject to specific conditions the signal present on the conductor
assumes the properties of a pure electromagnetic wave. We would like to give
our point of view on the modality of this transition, with the hope of
providing suggestions for ameliorating or projecting new devices.
