ABSTRACT:
The present invention relates to a method for producing an antenna comprising a conductive wire, formed by a wire, made of a conductive material, whose path has a helical shape. In accordance with the invention, such a method is characterized in that a print is formed in relief on one side of an element of an electrically insulating material such that the helical shape is generated by depositing the conductive material in this print.
