    [0001] The invention relates to non-contact or contact-free identification cards with contact and non-contact operation, provided with a metal plate for reinforcing or weighing down the card. STATE OF THE ART Most of the contactless smart cards or dual contact and contactless known dual contact cards comprise a plastic card body, an electronic module inserted into a card body cavity and provided with a plastic card body. microelectronic chip, and an antenna disposed in the card body and electrically connected to output pads of the microelectronic chip. Some of these smart cards have an antenna arranged in the card body, arranged to be in inductive coupling with the electronic module itself provided with an antenna. The card bodies have a standardized format according to the ISO 7810 standard, and they are generally made of plastic for reasons of cost and flexibility. A segment of the growing market is aimed at contactless smart cards, or dual contact and contactless smart cards, but with physical characteristics that are considered a more statutory or exclusive range, due to a higher weight which ensures a better grip. Plastic cards with a magnetic stripe and whose card body is provided with a metal layer are known. But there is currently no contactless smart card with such features. Indeed, as is known, the introduction of a metal plate into the card body has harmful consequences on the electromagnetic plane, since the metal plate constitutes a partial or even significant shielding of the electromagnetic waves likely to propagate. between the contactless smart card and the smart card reader. This has the possible consequence, either that the contactless communication performance of known cards are reduced, or that the card no longer operates in contactless mode only asymmetrically, that is to say that its operation in contactless mode is degraded on one side with respect to its operation on the other side. OBJECT OF THE INVENTION The general object of the invention is therefore to propose an optimized structure of a contactless smart card or dual chip card provided with a plate of a metallic material which weighs the card, without this conception. has perceptible adverse consequences on the operation of the smart card in contactless mode. A particular object of the invention is to provide a reinforced smart card 15 and weighed down, whose operation in contactless mode is as effective regardless of the face of the smart card oriented towards the card reader, or whatever either the orientation of the smart card relative to the contactless reader. SUMMARY OF THE INVENTION According to the principle of the invention, a metal plate is incorporated in the card body, and the smart card has two antennas in standardized format called ID1 and situated on either side of the metal plate. and each provided with coupling means connected in series with the antenna ID1 and constituted either by inductive coupling in the form of a concentrator antenna or by capacitive coupling. The antennas ID1 and their coupling means, as well as the metal plate, are arranged in such a way that the coupling means are coupled electromagnetically with each other and coupled with an antenna located on the microelectronic module of the smart card, so that the electromagnetic flux of the reader reaches at least one of the two antennas ID1 format and its coupling means. The electromagnetic flux of the reader thus reaches the antenna of the module via the antennas ID1 and their respective concentrator or capacitive coupling, whatever the orientation of the smart card. The subject of the invention is therefore a contactless or contact-free smart card with contact and non-contact operation, comprising a card body provided with a cavity in which is inserted an electronic module provided with a connected microelectronic chip. to an inductive or capacitive coupling means, characterized in that the card body consists of a stack of layers, at least two of which comprise a booster antenna, the different booster antennas being coupled together inductively and / or capacitively, and at least one of the booster antennas being coupled inductively and / or capacitively with the module coupling means, and in that the card body comprises a metal plate disposed between two of the layers provided with a booster antenna, said metal plate and said booster antennas being arranged so that at least one of the two booster antennas and the electronic module remain between them inductively and / or capacitively, despite the presence of the metal plate. This smart card structure and its variant embodiments therefore make it possible to ensure high quality radio frequency communication with a smart card reader, despite the presence in the structure of metal plates intended to weigh down and reinforce the card, and which without the invention would prevent the card from communicating effectively with the reader. According to a first embodiment of the invention, the electronic module is an inductive module provided with an antenna, and each booster is composed of an antenna in the so-called ID1 format, connected in series or in parallel with a concentrator antenna and with a capacity of adjustment of the resonant frequency of each booster, the concentrator antennas of each booster and the antenna of the electronic module being located substantially opposite one another so as to allow inductive coupling between the module and the two hubs, allowing communication between the module and a remote reader.
    [0002] Advantageously, said metal plate and the ferrite layers are provided with an opening in the overlap zone of the two concentrators, so as to facilitate the electromagnetic coupling between the two concentrators and to further reduce the electromagnetic shielding effect due to the metal plate. According to an alternative embodiment, the electronic module is an inductive module provided with an antenna and the chip card comprises a first booster provided with an ID1 format antenna connected in series with a first concentrator located substantially opposite the antenna of the module and a second concentrator, and said chip card comprises a second booster provided with an antenna in the ID1 format connected in series with a third concentrator, the second and third concentrators being located substantially opposite, so as to allow coupling between the first concentrator and the third concentrator via the second concentrator, without the first and third concentrators need to be located opposite. According to another embodiment of the smart card using an inductive electronic module provided with an antenna, the metal plate consists of two half-plates electrically insulated from each other. The card comprises a first booster comprising an antenna ID1 format and a concentrator antenna in series or in parallel and said first booster further comprising two metal closets for making capacitive connections with a first metal half-plate. The chip card further comprises a second booster comprising an antenna in ID1 format and also two metal cupboards for making capacitive connections with a second metal half-plate. According to another advantageous embodiment of the smart card according to the invention, the inductive module is replaced by a capacitive module, and in that the concentrator of the first booster located opposite the module is replaced by metal closets able to establish a capacitive link between said first booster and said capacitive module. This structure makes it possible to completely do without concentrators on the booster.
    [0003] According to the embodiments, the ID1 antennas of the boosters can be connected in parallel, and connected in parallel or in series with a capacity of adjustment of the resonant frequency of each booster. Of course, the thicker and thicker the metal plate, the greater the weighting effect will be. However, in the context of cards of usual thickness, in particular of corresponding thickness, the metal plate will have a thickness of the order of 100 micrometers to 400 micrometers, and the total thickness of the card will be between 680 micrometers and 950 micrometers, and preferably between 680 and 840 micrometers.
    [0004] The metal plate will have a weight of the order of 10 to 25 grams, so that the total weight of the chip card will be of the order of 15 to 30 grams, substantially greater than the weight of the order of 5 grams of contactless cards known. To achieve this result, it will take to manufacture the metal plate a heavy metal, including among tungsten, gold, iridium, osmium, platinum, or silver, preferably tungsten.

    [0005] Detailed Description For ease of understanding, the thicknesses of the material layers in the sectional views (Figures 4, 8, 12 and 16) are exaggerated with respect to the length of the map, but the thicknesses are substantially at the same scale. 'a real map. The identical elements in the different figures bear the same reference numbers. Referring to Figures 1 to 4 corresponding to a first embodiment of Io embodiment of the invention. The smart card has a substantially symmetrical stack consisting of a metal plate 11 surrounded on both sides by a ferrite layer 8, surmounted by a first booster antenna. An antenna "booster" or "booster" in the context of the present application means an antenna in the format ID1 connected in series or in parallel with a resonance capacitance, and connected in series or in parallel with a coupling means inductive or capacitive with another booster or with a microelectronic module, or with both. In the case of an inductive coupling means, it will be called a concentrator antenna or, for abuse of language, a "concentrator", namely an antenna 20 smaller than the antenna ID1 and intended to couple with a antenna of substantially the same size, namely the antenna of an inductive module or another concentrator. The antenna of a contactless smart card reader is typically larger than the antenna of the chip card module or the concentrator antenna, so that the coupling between the concentrator and the reader is negligible in front of the reader. coupling between the reader and the antenna ID1. Thus, in the case of FIG. 1, a first booster antenna (booster B1) is composed of an antenna 1 in the ID1 format connected in series with a concentrator antenna 2 and a capacity 3 for adjusting the resonance frequency of this antenna. first booster antenna. A second booster antenna 30 (Booster B2) is composed of an antenna 4 in ID1 format connected in series with a concentrator antenna 5 and a capacity 6 for adjusting the resonance frequency of this second booster antenna B2. Each booster B1, B2 is covered with a protective layer 9, 10, and one of the two protective layers 10 comprises a cavity 12 receiving a microelectronic module 7 which may be a conventional contactless smart card module, or a module with dual contact and non-contact operation. Figure 1 does not show some additional layers not related to the invention, including glue layers to bind the various components. They are represented by way of example in the cross-sectional view of FIG. 4. In order to weigh down the smart card, the metal plate 11 is made of a heavy metal, taken in particular from tungsten, gold and silver. , platinum, iridium, osmium, it being understood that tungsten undoubtedly presents the best compromise between a high weight and a reasonable cost. The ferrite layers 8 serve to attenuate the electromagnetic disturbances due to the presence of the metal plate. In addition, in this first embodiment of the invention, the two concentrators 2, 5 are superimposed and located opposite one of the other to ensure a good electromagnetic connection between the two boosters Bi, B2. In order to further optimize this connection and to minimize disturbances due to the metal plate, the metal plate 11 and the ferrite layers 8 have openings 12 situated opposite the concentrators 2.5, which allows easy passage of the flux electromagnetic between the two boosters, via their two concentrators and the openings 12 of the ferrite plates and the metal layer 11. The outer layers 9,10 protection are known per se in the field of smart cards and are for example in one plastic and transparent material. As seen in Figure 4, several upper layers form an assembly 10, for example a white core surrounded on both sides by a transparent layer. In the same way, two layers of plastic material form a lower protection assembly 9. The assembly 10 comprises a cavity receiving the microelectronic module 7, so that the thickness of the upper assembly 10 may be slightly greater than that of the lower assembly 9, but this structural difference on plastic layers does not affect the electromagnetic operation of the smart card. Figure 4 corresponds to a section of Figure 1 along the section line A-A through the opening 12 of the metal plate 11, which is filled with a plastic material. It can be seen that in this zone, the concentrators 2, 5 can communicate through the opening 12 or the plastic material, without being obstructed by the metal plate 11 which does not extend opposite the concentrators.
    [0006] Thus, the physical structure of the embodiment of FIGS. 1 and 4 achieves the fixed objective of integrating a metal plate 11 into the smart card in order to weigh it down, while having a minimal impact on the electromagnetic operation of the card. . It is observed in particular that, thanks to the electromagnetic link between the two boosters B1, B2 via their respective concentrator 2.5, the operation of the card with a reader will be quasi-symmetrical, and independent of the orientation of the card with respect to the despite the presence of the metal plate 11. As shown in the equivalent electrical diagrams of Figures 2 and 3, each hub 2.5 can be connected in parallel with its resonance capacity 3.6 (Figure 2), or in series with it (Figure 3). Basically, each booster B1, B2 is an RLC circuit that can be of serial or parallel type depending on the application and the desired communication performance. The equivalent diagram of the communication stage of the microelectronic module 7 of the smart card, constituted by an RLC circuit whose antenna is noted 15, is also represented. FIGS. 5 to 8 represent a variant of the preceding embodiment (FIG. FIGS. 1 to 4), in which the first booster B1 comprises two concentrators 2.2 ', connected in series or in parallel with a capacity 3 for adjusting the resonance frequency of booster Bi. The booster B2 is not modified compared to the previous case, except that the position of the concentrator 5 booster B2 is no longer opposite the concentrator 2 as in the previous case, but in front of the concentrator 2 '. The concentrator 2 'of the booster B1 and the concentrator 5 of the booster B2 are also opposite an opening 12' arranged in the metal plate 11, which ensures a possibility of communication between the two boosters B1, B2, while the concentrators 2.5 boosters B1, B2 are not themselves facing each other. It is therefore observed that in each of the preceding cases (FIGS. 1 to 4 and FIGS. 5 to 8), the communication between the boosters B1, B2 located on either side of the metal plate 11 requires the presence of an opening 12, 12 'in this plate, which slightly reduces the desired weight effect thanks to the metal plate. The third and fourth embodiments, shown in Figures 9 to 15, improve the solution of the invention on this particular point, by replacing the single metal plate 11 provided with an opening 12 or 12 'by two metal half-plates 11a, 11b without opening (FIG. 9), electrically insulated from each other by a cut-out 18. FIG. 12 is a common sectional view for the embodiments of FIGS. 9 and 13. In order to allow communication between the two boosters B1 , B2 located on either side of the metal plates 11a, 11b, the structure of these boosters is also modified, so that the communication between them is done by capacitive effect and no longer via concentrator antennas. For this purpose, the booster B1 comprises metal cupboards 16a, 16b, and booster B2 comprises metal cupboards 17a, 17b. These metal cupboards make it possible to form, with the metal half-plates 11a, 11b, capacitors 13, 13 ', 14, 14' making it possible to produce, through openings 15a, 15b, 15c, 15d arranged in the ferrite layers 8 , the capacitive connection between the two boosters B1, B2 on either side of the two metal half-plates 11a, 11b. The advantages of this embodiment lie in the absence of an opening 12 in the metal plates 11a, 11b, which maximizes the desired weight effect on the smart card. In addition, if we neglect the effect of the field of the reader recovered directly by the antenna 15 of the module 7 and by the concentrator 2, the operation of the smart card remains quasi-symmetrical and independent of the orientation of the card. chip compared to the reader. The embodiment of FIGS. 13 to 15 differs from the previous one (FIGS. 9 to 12) only in the use of a capacitive module 17 instead of the inductive module 7. This embodiment retains the advantages associated with the two metal half-plates 11a, 11b, but adds to it a completely symmetrical operation because the capacitive module 17 does not recover any magnetic field of the reader, unlike the inductive module 7.
    [0007] FIG. 16 in section shows an alternative embodiment which, unlike the previous modes (FIGS. 4, 8 and 12), comprises a solid metal plate 11 'and two ferrite sheets 8' which represent almost the entire surface of the Smartcard. This card comprises two electronic modules without contact, independent, and unable to communicate with each other radiofrequency because of the presence of the metal plate 11 '. These modules each communicate independently with a smart card reader. This embodiment has a higher cost due to the presence of two microelectronic modules, but it is of a simple construction and allows to maximize the weight of the card for a given thickness. Advantages of the invention Finally, the invention proposes a smart card design to achieve the desired goals. It comprises a plate made of a heavy material, typically a metal of the tungsten type or equivalent, and a structure making it possible to cancel or limit the shielding effects of this metal plate with respect to the radiofrequency signals to be exchanged with a card reader. smart.
    [0008] In particular, the structure of the smart card according to the invention makes it possible to obtain, on each side of the smart card, communication performance 12 3032294 RF which is entirely satisfactory with respect to the standards imposed. In addition, these performances are, according to the application requirements, substantially symmetrical so that the user can present the smart card in any orientation relative to the smart card reader. 5
