Definitions

  • the antenna comprises a single assembly consisting of a plurality of turns associated with an insulating support, that is to say a single antenna element.
  • the reading and writing distance is maximum and constant regardless of the angle between the direction of the magnetic field and the section of the turns of each of the three sets.
  • reading and writing are also possible given the arrangement of the three pluralities of turns forming between them angles of 120 °.
  • the antenna according to the invention can be manufactured according to various methods which essentially depend on its configuration.
  • Example 2 By carrying out the process described in Example 2, a 4-layer printed circuit consisting of two double-sided circuits with metallized holes is produced, which corresponds to a first and a second set of turns associated with their respective insulating support. , i.e., a first and a second antenna element.
