Dipole antennas have been invented a hundred years ago. Nevertheless, what really happens in their proximity during emission (the so-called nearfield) 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.
