Definitions

  • the present invention relates to an NFC communication device for insertion into a communication terminal.
  • the invention relates to devices for giving terminals radiofrequency and / or NFC contactless features without modification of the terminal including mobile phones.
  • the object of the invention is to solve this drawback.
  • the principle of the invention consists in providing these radio frequency devices with a foldable and / or extensible and / or removable antenna.
  • This antenna will be integrated in small objects; It is expandable manually and / or automatically in particular by means of a tongue and / or elastic or spring return means.
  • the invention therefore relates to a device for providing a terminal with all or part of radio frequency functionalities, said device comprising a connector to the terminal and means performing an antenna interface function;
  • a device 1 comprises a radiofrequency antenna 2 and intended to provide a terminal with all or part of radiofrequency functionalities.
  • the functionalities are of the NFC (near field communication) type.
  • the device may include a memory and / or a microprocessor.
  • the device comprises connection means to a physical interface of a terminal 6 which does not have radiofrequency function. This terminal has against, an interface or port for receiving the device.
  • the interface of the terminal is able to receive a flash card SD type (Sandisk company).
  • cards or memory storage objects of different form factor and / or implementing different communication protocols may also be covered by the invention and / or replace the device of the example, including MMC, ("Multimedia card”), or type CF ("Compact flash”), or even USB sticks.
  • MMC Multimedia card
  • type CF Compact flash
  • the device in the example comprises a format and connections conform to an SD card so as to be inserted in a suitable housing of the terminal 6 capable of receiving an SD card.
  • the device comprises all or part of the functionalities necessary for the realization of an NFC radio frequency communication.
  • the device comprises means capable of converting the radio frequency signals into signals that can be used by the terminal.
  • the device only completes some of the features already provided in the terminal.
  • the device comprises at least the extensible or telescopic antenna part or can be deployed and connected directly to the contact pads of the device. If necessary, the antenna can connect ranges of the device not affected by the current standard.
  • the device comprises means for extending the antenna; these extension means are capable of unfolding and / or extending the antenna.
  • the card includes an antenna that can expand or expand.
  • the card may include connection means 13 to an external antenna ( Fig. 6 ).
  • the antenna is arranged in the example in a portion 9 disposed at the rear of the card 3 which is opposite the connection pads 4 for connecting the terminal.
  • the antenna 2 here forms a loop which can extend from the inside of the card through orifices (not shown) on the rear edge 3a of the card.
  • the antenna may include a tab 6 or gripping handle of the antenna (more rigid part of the antenna) which remains outside the card when the antenna is retracted inside the card.
  • the tongue can remain accessible in particular in a cavity 7 opening on one of the largest major surfaces of the card.
  • the card may also include means for retracting the antenna.
  • the card may comprise a retractable mini crank (not shown) connected to one or more winding coils 8 inside the card. These extension means can be manually operable. Tracks or conductive elements can connect the conductive axes of these coils connected to the wire to connect the coils to all or part of the additional radio frequency means of the card or terminal.
  • the extension means comprise elastic return means or retraction means. They may comprise a return spring or torsion of known type adapted for this purpose and coupled to the coils.
  • the antenna is formed to be telescopic or expandable.
  • the extension means of the antenna may comprise or constitute an electrical winding associated with an elastic wire 5E.
  • the antenna wire 5 may comprise a solenoid of conductive wire wound around a textile or elastic strand 5E for example disposed in the center of the coil.
  • the antenna comprises a copper wire of less than 80 microns section and is wrapped around a stretchable elastic textile wire symbolized by the arrow 5E inside the solenoid.
  • the winding of the copper wire forms a solenoid with a contiguous turn 5 ( Fig. 2 ).
  • the copper solenoid stretches and the turns become torn.
  • the antenna wire obtains its final electromagnetic characteristics when the textile yarn is fully stretched.
  • the wire can be stored in a card slot opening on the back of the card.
  • the solenoid 5 takes its place in the cavity on loosening of the antenna.
  • the antenna wire can be fixed on a support to stabilize it, in particular with adhesive fixatives.
  • the antenna can be fixed on the terminal or around the terminal with, if necessary, fixing pads if necessary.
  • the elasticity of the antenna may be sufficient to maintain the antenna around the terminal from the map.
  • One or more turns of the antenna wire may be performed around the terminal housing.
  • the elasticity of the antenna arranged around the terminal also keeps the card in the terminal when it is inserted into a slot opening on the outside of the housing.
  • the card is inserted in the terminal 6.
  • the terminal 6 Preferably, it is protruding from the terminal housing.
  • the card is inside a housing of the terminal consisting of two shells. Under these conditions, it is expected that the wire is fine enough to exit the housing at the junction between the two shells without interfering with the nesting of the shells.
  • the antenna wire is fixed, with adhesive pads, inside one of the removable shells before being assembled to the other shell.
  • the card may comprise a single winding coil 8; when the antenna wire is retracted, the handle or tab 6 enters its housing 7 at the rear of the card.
  • the external format of an SD memory card is retained.
  • this is the type SD memory card whose rear portion opposite the connections 4 has an extension 9 of the housing.
  • This extension 9 increases the length and / or the width and / or thickness of the card without interfering with its insertion into the terminal.
  • This extension comprises the means of retracting or rewinding 8 of the antenna including the two coils 8 in this example.
  • the extension 9 may be sized to include the solenoid 5 replacing the coils 8.
  • This extension may include other communication interfaces or connectors of the card including WIFI communication, LAN WLAN, in addition to or in place of a NFC communication.
  • the device 3a of the invention comprises a connector 13 for connecting a radio frequency antenna 2a or other communication interface.
  • the antenna 2a has a connector 12 so as to connect the card. It comprises a support or substrate 10 preferably flexible and insulating, especially plastic or paper and preferably thin.
  • This embodiment makes it possible to increase the communication capabilities of the card while providing for withdrawal of the antenna in case of non-use of the NFC function.
  • the card already has an internal antenna of reduced dimensions but also offers the possibility of increasing the NFC performance by providing a connection to another removable antenna.
  • the antenna connection automatically disconnects the reduced antenna.
  • the antenna can be fixed by adhesive or otherwise on the terminal, especially inside the housing or outside.
  • the antenna can be manufactured using a wired technology (wire-based or engraved or screen-printed by implementing electronic tag technology.
  • the antenna may comprise a flexible portion 11 connecting between the turns and the antenna connector 12 so as to facilitate connection to the card and allow, if necessary, redirection of the antenna to the outside of the terminal housing.
  • This part may take the form of a sheet of flat wire, in particular plastic a few millimeters wide (3-10 mm) and extremely thin for example of the order of 80 microns to 0.5 mm so as to pass between the junction or interface of two shells of a telephone case.
  • the device can thus constitute a radiofrequency adapter via a memory card or a memory card connector for a communication terminal.
