A la figure 1 un dispositif 1 conforme à l'invention comporte une antenne radiofréquence 2 et destiné à doter un terminal de tout ou partie de fonctionnalités radiofréquences. En particulier, les fonctionnalités sont du type NFC (near field communication).To the figure 1 a device 1 according to the invention comprises a radiofrequency antenna 2 and intended to provide a terminal with all or part of radiofrequency functionalities. In particular, the functionalities are of the NFC (near field communication) type.

Le dispositif peut comprendre une mémoire et/ou un microprocesseur. Le dispositif comprend des moyens de connexion vers une interface physique d'un terminal 6 qui n'est pas doté de fonction radiofréquence. Ce terminal possède par contre, une interface ou port destiné à recevoir le dispositif. Dans l'exemple, l'interface du terminal est apte à recevoir une carte à mémoire flash du type SD (de la société Sandisk).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. In the example, the interface of the terminal is able to receive a flash card SD type (Sandisk company).

D'autres cartes ou objets de stockage à mémoire de masse de différents facteur de forme et/ou mettant en oeuvre différents protocoles de communication, peuvent également être couverts par l'invention et/ou remplacer le dispositif de l'exemple, notamment MMC, ("Multimédia card"), ou du type CF ("Compact flash"), voire clés USB.Other 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.

Le dispositif dans l'exemple comporte un format et des connexions conformes à une carte SD de manière à être inséré dans un logement adapté du terminal 6 apte à recevoir une carte SD.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.

Le dispositif selon un mode de réalisation comporte tout ou partie des fonctionnalités nécessaires à la réalisation d'une communication radiofréquence NFC. Le dispositif comporte des moyens aptes à convertir les signaux radiofréquences en signaux exploitables par le terminal.The device according to one embodiment 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.

Le cas échéant, le dispositif ne fait que compléter une partie des fonctionnalités déjà prévues dans le terminal. En particulier, le dispositif comporte au moins la partie antenne extensible ou télescopique ou pouvant être déployée et connectée directement aux plages de contact du dispositif. Le cas échéant, l'antenne peut connecter des plages du dispositif non affectés par la norme en vigueur.If necessary, the device only completes some of the features already provided in the terminal. In particular, 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.

Selon une caractéristique de l'invention, le dispositif comprend des moyens d'extension de l'antenne; ces moyens d'extension sont capables de déplier et/ou d'étendre l'antenne. Autrement dit, la carte comprend une antenne qui peut s'étendre ou se déployer. En alternative, la carte peut comprendre des moyens de connexion 13 à une antenne externe (fig. 6).According to one characteristic of the invention, the device comprises means for extending the antenna; these extension means are capable of unfolding and / or extending the antenna. In other words, the card includes an antenna that can expand or expand. Alternatively, the card may include connection means 13 to an external antenna ( Fig. 6 ).

L'antenne est disposée dans l'exemple dans une partie 9 disposée à l'arrière de la carte 3 qui est opposée aux plages de connexions 4 destinées à connecter le terminal.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.

L'antenne 2 forme ici une boucle qui peut s'étendre de l'intérieur de la carte par des orifices ménagés (non représentés) sur la tranche arrière 3a de la carte.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.

L'antenne peut comporter une languette 6 ou poignée de préhension de l'antenne (partie plus rigide de l'antenne) qui demeure à l'extérieur de la carte quand l'antenne est rétractée à l'intérieur de la carte. La languette peut rester accessible notamment dans une cavité 7 débouchant sur une des plus grandes surfaces principales de la carte.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.

La carte peut comprendre également des moyens qui permettent de rétracter l'antenne. Selon un mode de réalisation, la carte peut comprendre une mini manivelle escamotable (non représentée) reliée à une ou des bobines d'enroulement 8 à l'intérieur de la carte. Ces moyens d'extension peuvent être actionnables manuellement. Des pistes ou éléments conducteurs peuvent relier les axes conducteurs de ces bobines reliés au fil pour connecter les bobines à tout ou partie des moyens complémentaires radiofréquences de la carte ou du terminal.The card may also include means for retracting the antenna. According to one embodiment, 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.

Au lieu et place de la manivelle, selon un autre mode de réalisation, plus automatique, les moyens d'extension comprennent des moyens de rappel élastiques ou moyens de rétractation. Ils peuvent comprendre un ressort de rappel ou de torsion de type connu adapté à cet effet et couplé aux bobines.Instead of the crank, according to another embodiment, more automatic, 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.

Selon un autre mode de réalisation, l'antenne est formée de manière à être télescopique ou extensible.In another embodiment, the antenna is formed to be telescopic or expandable.

Les moyens d'extension de l'antenne peuvent comprendre ou constituer un bobinage électrique associé à un fil élastique 5E. Comme illustré à la figure 2, le fil d'antenne 5 peut comporter un solénoïde de fil conducteur enroulé autour d'un brin textile ou élastique 5E par exemple disposé au centre du bobinage. Dans l'exemple, l'antenne comprend un fil de cuivre de section inférieure à 80 µm et est enroulé autour d'un fil textile élastique étirable symbolisé par la flèche 5E à l'intérieur du solénoïde.The extension means of the antenna may comprise or constitute an electrical winding associated with an elastic wire 5E. As illustrated in figure 2 , 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. In the example, 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.

L'enroulement du fil cuivre forme un solénoïde à spire jointive 5 (fig. 2). Lorsque le fil textile est étiré, le solénoïde de cuivre s'étire et les spires se déjoignent. Le fil d'antenne obtient ses caractéristiques électromagnétiques finales lorsque le fil textile est entièrement étiré. Le fil peut être rangé dans un logement de la carte débouchant à l'arrière de la carte. Le solénoïde 5 prend sa place dans la cavité au relâchement de l'antenne.The winding of the copper wire forms a solenoid with a contiguous turn 5 ( Fig. 2 ). When the textile yarn is stretched, 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.

En utilisation, le fil d'antenne peut être fixé sur un support pour le stabiliser, notamment avec des fixateurs adhésifs.In use, the antenna wire can be fixed on a support to stabilize it, in particular with adhesive fixatives.

Alternativement, l'antenne peut être fixée sur le terminal ou autour du terminal avec le cas échéant des pastilles de fixation si nécessaire. L'élasticité de l'antenne peut être suffisante pour maintenir l'antenne autour du terminal en partant de la carte. Un ou plusieurs tours du fil d'antenne peuvent être effectuées autour du boîtier du terminal. L'élasticité de l'antenne disposée autour du terminal permet aussi de maintenir la carte dans le terminal quand celle-ci est insérée dans une fente débouchant sur l'extérieur du boîtier.Alternatively, 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.

A la figure 3, la carte est insérée dans le terminal 6. De préférence, elle est saillante par rapport au boîtier du terminal.To the figure 3 , the card is inserted in the terminal 6. Preferably, it is protruding from the terminal housing.

Dans une variante, la carte est à l'intérieur d'un boîtier du terminal composé de deux coques. Dans ces conditions, il est prévu que le fil soit assez fin soit pour sortir du boîtier à la jonction entre les deux coques sans gêner l'emboîtement des coques.In a variant, 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.

Alternativement, le fil d'antenne est fixé, avec des pastilles adhésives, à intérieur d'une des coques amovibles avant d'être assemblé à l'autre coque.Alternatively, the antenna wire is fixed, with adhesive pads, inside one of the removable shells before being assembled to the other shell.

A la figure 4, la carte peut comporter une seule bobine d'enroulement 8; lorsque le fil d'antenne est rétracté, la poignée ou languette 6 rentre dans son logement 7 à l'arrière de la carte. Ainsi, le format externe d'une carte à mémoire de type SD est conservé.To the figure 4 , 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. Thus, the external format of an SD memory card is retained.

A la figure 5, un autre mode de réalisation du dispositif est représenté. En fait, il s'agit ici de la carte à mémoire de masse de type SD dont la partie arrière opposée aux connexions 4 comporte une extension 9 du boîtier. Cette extension 9 augmente la longueur et/ou la largeur et/ou épaisseur de la carte sans gêner son insertion dans le terminal.To the figure 5 another embodiment of the device is shown. In fact, 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.

Cette extension comporte les moyens de rétractation ou rembobinage 8 de l'antenne notamment les deux bobines 8 dans cet exemple. L'extension 9 peut être dimensionnée pour comprendre notamment le solénoïde 5 remplaçant les bobines 8. Cette extension peut comprendre d'autres interfaces de communication ou connecteurs de la carte notamment communication WIFI, réseau local WLAN, en plus ou à la place d'une communication NFC.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.

A la figure 6, le dispositif 3a de l'invention selon un autre mode de réalisation, comporte un connecteur 13 destiné à connecter une antenne radiofréquence 2a ou autre interface de communication.To the figure 6 , the device 3a of the invention according to another embodiment, comprises a connector 13 for connecting a radio frequency antenna 2a or other communication interface.

L'antenne 2a comporte un connecteur 12 de manière à connecter la carte. Elle comporte un support ou substrat 10 de préférence souple et isolant, notamment en plastique ou papier et de préférence fin.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.

Ce mode de réalisation permet d'augmenter les capacités de communication de la carte tout en prévoyant un retrait de l'antenne en cas de non utilisation de la fonction NFC.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.

Le cas échéant, la carte comporte déjà en interne une antenne de dimensions réduite mais offre aussi la possibilité d'augmenter les performances NFC en prévoyant une connexion à une autre antenne amovible. De préférence, la connexion de l'antenne déconnecte automatiquement l'antenne réduite.If necessary, 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. Preferably, the antenna connection automatically disconnects the reduced antenna.

L'antenne peut être fixée par adhésif ou autre sur le terminal notamment à l'intérieur du boîtier voire à l'extérieur.The antenna can be fixed by adhesive or otherwise on the terminal, especially inside the housing or outside.

L'antenne peut être fabriquée selon une technologie filaire (à base de fil électrique ou gravée ou obtenue par sérigraphie en mettant en oeuvre une technologie des étiquettes électroniques.The antenna can be manufactured using a wired technology (wire-based or engraved or screen-printed by implementing electronic tag technology.

L'antenne peut comporter une partie souple 11 de liaison entre les spires et le connecteur d'antenne 12 de manière à faciliter la connexion à la carte et permettre le cas échéant une redirection de l'antenne vers l'extérieur du boîtier du terminal. Cette partie peut prendre la forme d'une nappe de fil plate, notamment en plastique de quelques millimètres de large (3-10 mm) et extrêmement fine par exemple de l'ordre de 80 µm à 0,5 mm de manière à passer entre la jonction ou interface de deux coques d'un boîtier de téléphone.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.

Le dispositif peut ainsi constituer un adaptateur radiofréquence via une carte à mémoire ou un connecteur de carte à mémoire pour un terminal de communication.The device can thus constitute a radiofrequency adapter via a memory card or a memory card connector for a communication terminal.
