Antenna for portable devices perfected, characterized by being composed of a conductor that has been advantageously wound in helix, cylindrical or conical, as a long spring, to reduce its extension with the same length, which is covered by an insulating sheath, elastic and flexible, tightly adjoined to it, suitably topped by the distal end, while by the proximal end said spring, taking advantage of the screw arrangement of its propeller, is screwed the male part, externally threaded, of the clamping piece and connection to the apparatus, which part, in its main part, from which the threaded male starts, has a knurled or fluted and a blind hole, internally threaded hole or a radiofrequency connector, thus constituting the coupling means and fixation.
