Definitions

  • the invention relates to a magnetic field antenna for a radio frequency transponder.
  • radiofrequency antenna supports such as electronic passports, travel documents, smart cards, tickets, radio frequency tags, radio frequency transponders, insert (or inlay).
  • Such objects may in particular comply with the ISO / IEC 14443 standard.
  • the antenna supports constituted by a sheet of the passport booklet or the cover, it was found by the inventors of the weak points during the test below of mechanical resistance including bending and twisting (WG3TF4_N0232_ Test Specifications for MPRs V3.2 ⁇ 5.7)
  • the problem identified by the inventors is that the natural tendency to fold P that a cover spreads to the layers containing the antenna can thus cause the rupture thereof by shearing.
  • the object of the invention is to propose a transponder antenna which is more resistant to the abovementioned bending stresses.
  • the folding tendency was localized at a median located substantially perpendicular to a passport booklet hinge.
  • the inventors' studies have shown that the closer the antenna wires are to each other, the more resistant and crease resistant the antenna is .
  • the invention consists in bringing the wires at least only in the identified zone of stress so as not to modify the performances. radiofrequency of the antenna while increasing its resistance to bending / twisting.
  • the subject of the invention is therefore a magnetic field antenna comprising a plane support with a longitudinal edge, an electromagnetic coupling receiving antenna on the support, said edge being intended to be parallel to a booklet binding, said antenna comprising turns parallel and perpendicular respectively extending parallel and perpendicular to the longitudinal edge;
  • the antenna is distinguished in that said parallel turns have an inter-turn spacing close to the inter-turn spacing of the perpendicular turns.
  • the invention also relates to an electronic portable object comprising the antenna above; It can preferably be a passport, a booklet, the antenna being carried by a sheet or cover of the booklet or passport.
  • a booklet 1 including passport is subjected to a bending test as shown in the figure by a pressure F exerted in the center and the edges in reaction.
  • the figure 2 illustrates the booklet in profile showing the binding 2 and the opposite edge 3.
  • a passport sheet of the prior art has a plane support 4 supporting a radio frequency transponder, a longitudinal edge 2 near the passport binding, an electromagnetic coupling receiving antenna 14 on the support.
  • the antenna has turns surrounding a central coupling surface; The turns extend at least partly parallel and close to the longitudinal edge 2.
  • the antenna is here made of a wire embedded in the support.
  • the antenna is connected to an electronic micromodule comprising a radiofrequency integrated circuit chip 15 via the connection ends 16 and 17. It is not excluded to provide other antenna production techniques known to the skilled in the art, such as embroidery, already coiled antenna transfer, etching.
  • the invention preferably targets wire antennas of substantially constant section (or diameter).
  • the invention can provide a thinning of the width of the turns at the zone 7 in addition to a reduced inter-turn spacing.
  • the antenna can be considered in the absolute only by the turns but also with its substrate for the maintenance of the turns between them. It can include at least the turns themselves and the substrate.
  • antenna within the meaning of the invention, it is possible also speak of insert (inlay in English) antenna or radio frequency transponder with or without integrated circuit chip connected.
  • the antenna can be finished or semi-finished insofar as it can be intended to be connected or not to one or more electrical components, electronic.
  • the antenna may be bare (not connected to an integrated circuit chip);
  • the antenna can be connected to a capacity.
  • the turns of the antenna or at least those arranged along the edge 2 adjacent the binding, have a spacing substantially constant spacing.
  • the spacing is for example commonly between 0.5 and 2 mm for son diameter between 50 and 150 microns.
  • a region 7 of the turns located near the longitudinal edge 2 is a region particularly exposed to a stress axis as symbolized by an arrow 5.
  • an antenna support 4 carries an antenna 14 extended on or parallel to one of its main surfaces;
  • the antenna support is substantially in accordance with the preceding figure with a difference described hereinafter.
  • the edge 2 is intended to be parallel to a passport booklet binding; It can be seen that the antenna 14 in the form of a rectangle comprises parallel (large side of the rectangle) and perpendicular (small sides of the rectangle) turns extending respectively parallel and perpendicular to the longitudinal edge (2).
  • At least a portion of the turns disposed in a region 7 close to the edge 2 adjacent to the binding has an inter-turn spacing ES close to the normal spacing EL of the turns of the other regions.
  • the parallel turns have, at least at a place or region 7, a close inter-turn spacing (ES) with respect to the inter-turn spacing (EL) of the perpendicular turns. (See Fig. 10-11 )
  • the surface portion 7 is situated on a transverse median of the support 4, extending perpendicularly to the longitudinal edge 2.
  • the edge 2 is intended to be adjacent to a hinge or binding of the booklet.
  • the close turns have an inter-turn spacing ES of between 0.1 and 0.5 mm;
  • the unmated turns, for their part, have an inter-turn spacing EL between 0.5 and 2 mm.
  • the wires have a diameter of between 50 and 150 ⁇ m.
  • substantially the entire edge of the antenna adjacent to the binding or the edge 2 is made with a reduced inter-turn spacing with respect to particular portions of turns disposed perpendicularly to the edge 2.
  • the antenna comprises two portions 9 and 10 located in the extension of the axis of stress 5.
  • the portion 10 is located on the opposite turns to those close to the fold.
  • the two sides 11, 12 of the antenna extending parallel to the edge adjacent to the fold 2 are made with a reduced inter-turn spacing ES compared to the turns oriented transversely to the edge 2.
  • the turns of the region 7 not only have a reduced spacing ES but they are all shifted towards the inner turn of the antenna 14 so that the outer turn of the antenna in the region 7 is is further away from the edge 2 than the outer turn of the remaining portions of the antenna parallel and adjacent to the edge 2.
  • the turns of region 7 are brought closer to the inner turn of the antenna.
  • the outer turn of the region 7 is at a distance B from the edge 2 which is greater than a distance A from the edge 2 to the portions of external turn parallel to the edge 2, situated outside the region 7.
  • the normal inter-turn spacing EL of an antenna is indicated in the regions not subjected to the bending stress (for example in the portions of the antenna oriented perpendicularly to the binding or edge 2).
  • the EL values are between 0.5 and 2 mm.
  • the ES values are between 0.1 and 0.5 mm.
  • ES is between 0.1 and 0.4 mm.
  • the number of turns is indicative only in the example between 3 - 7.
  • the invention may relate to any portable electronic object comprising the transponder described above.
  • it may include a passport, a booklet, the transponder being carried by a sheet or cover of the booklet.
