<p>An antenna for metal detectors utilizable as a transmitter and/or receiver comprising multiple cylindrical supports (6,7,8) in insulating material each of which supports a winding (1,2,3) formed by a set of coils substantially in the form of a parallelogram of helicoid or flat extension, positioned concentrically or otherwise and connected in an adequate way to excitation and/or detection means for the generation of magnetic fields and/or the detection of their variations. The system of multiple cylindrical supports with the respective sets of coils is housed inside a tubular insulating support (5) suitable to protect the windings from possible external stress of mechanical nature. <IMAGE></p> |
