The invention concerns an inductive element for forming an electromagnetic transponder antenna, comprising a first group of mutually parallel conductors coplanar in a first plane, a second group of mutually parallel conductors coplanar in a second plane parallel to the first plane, and an insulating material separating the two groups of conductors, one end of each conductor of the first group being connected to one end of a conductor of the second group whereof the other end is connected to one end of another conductor of the first group, the connections between the conductors being conductive via holes in the thickness of the insulating material.
