En particulier, l'invention vise un dispositif de communication radiofréquence comprenant un circuit électronique sur un corps support et une antenne radiofréquence reliée au moins en partie au circuit électronique et définissant une surface de couplage électromagnétique.In particular, the invention relates to a radiofrequency communication device comprising an electronic circuit on a support body and a radiofrequency antenna connected at least in part to the electronic circuit and defining an electromagnetic coupling surface.

Plus particulièrement, l'invention vise de tels dispositifs comportant une fonction USB et radiofréquence RF, notamment selon la norme ISO 14443, ISO 15693, ou de type NFC (ISO18092, ISO21481, etc.)More particularly, the invention is directed to such devices comprising a USB and RF radio frequency function, in particular according to the ISO 14443, ISO 15693 or NFC (ISO 18092, ISO 21448, etc.) standard.

Elle trouve application notamment au chargement de données par internet, notamment de droits d'accès, abonnement, à des services tels que transport, téléphonie, par une interface à contact et utilisation de ces données dans un mode radiofréquence en relation avec des bornes radiofréquences ou inversement.It finds application in particular to the loading of data over the Internet, including access rights, subscription, to services such as transport, telephony, a contact interface and use of these data in a radio frequency mode in connection with radiofrequency terminals or Conversely.

De tels dispositifs sont connus parmi notamment des clés USB qui embarquent une fonction radiofréquence RF pour des applications de contrôle d'accès. Un exemple d'un dispositif USB avec une antenne amovible est donné dans le document WO 2006/022353 , pour lequel l'antenne amovible est intégrée dans un capuchon de protection de la prise USB. Dans ce dispositif, l'antenne est enlevée de la prise USB et insérée en utilisation sur l'autre extrémité du dispositif qui comporte des contacts dédiés. Bien que décrit en relation avec l'USB, l'invention s'applique à tout dispositif de communication à contacts électriques notamment contacts linéaires tels que décrits dans les standards ou normes MMC, SD, Express card, ou ISO 7816 ou autre. Dans tout le document, par simplification, le terme USB signifie également tout autre standard ou protocole de communication différent d'USB.Such devices are known among in particular USB keys that embark RF radio function for access control applications. An example of a USB device with a detachable antenna is given in the document WO 2006/022353 , for which the detachable antenna is integrated into a protective cap of the USB socket. In this device, the antenna is removed from the USB socket and inserted into use on the other end of the device which has dedicated contacts. Although described in connection with USB, the invention applies to any communication device with electrical contacts including linear contacts as described in standards or standards MMC, SD, Express card, or ISO 7816 or other. Throughout the document, for simplicity, the term USB also means any other standard or communication protocol different from USB.

La capacité à télé-alimenter à travers l'antenne la puce radiofréquence (RFID) va dépendre de la surface de l'antenne, il est donc souhaitable d'avoir un dispositif USB d'une grande surface, ce qui est en contradiction avec l'usage classique des dispositifs USB qui sont en général petits. Ces dispositifs USB auront donc une efficacité ou portée assez réduite de l'ordre de quelques centimètres, l'antenne ayant une surface de couplage au plus égale à la surface ou encombrement de la clé, généralement 2 à 3 cm2.The ability to tele-power through the antenna the radio frequency chip (RFID) will depend on the antenna surface, so it is desirable to have a USB device of a large area, which is in contradiction with the 'use classic USB devices that are usually small. These USB devices will have an efficiency or range reduced to a few centimeters, the antenna having a coupling surface at most equal to the surface or size of the key, generally 2 to 3 cm2.

L'antenne est positionnée par rapport à ce circuit de manière à avoir une surface de couplage qui soit le moins possible en regard du circuit.The principle of the invention consists in a first radiofrequency mode of use, to deport or have the antenna of the RF device out of one or more electronic circuits or printed circuit boards (PCB), so as to reduce interference or disturbances with conductive parts of a circuit. The antenna is positioned relative to this circuit so as to have a coupling surface that is as little as possible facing the circuit.

Autrement dit, le dispositif comporte une première configuration fonctionnelle de communication radiofréquence dans laquelle l'antenne en forme de spires présente au moins une portion de surface de couplage (à l'intérieur de la spire la plus large) dépourvue de circuit électronique directement en regard;In other words, the device comprises a first radiofrequency communication functional configuration in which the coil-shaped antenna has at least one coupling surface portion (inside the widest turn) devoid of an electronic circuit directly opposite. ;

D'autre part, en mode d'utilisation à contact électrique (notamment USB), le dispositif comprend de préférence, une configuration fonctionnelle dans laquelle l'antenne est agencée de manière à libérer de l'encombrement du dispositif ou du moins, ne pas gêner sa connexion ou une autre connexion de clés USB aux autres ports ou connecteurs de terminaux ou ordinateur.On the other hand, in the electrical contact mode of use (in particular USB), the device preferably comprises a functional configuration in which the antenna is arranged so as to free the bulk of the device or at least not interfere with its connection or other USB stick connection to other ports or terminal connectors or computer.

Selon un mode de réalisation plus concret, l'invention consiste à avoir une antenne qui soit mobile et/ou amovible et/ou souple par rapport au circuit électronique ou un corps principal (généralement rigide) du dispositif.According to a more concrete embodiment, the invention consists in having an antenna that is mobile and / or removable and / or flexible relative to the electronic circuit or a main body (generally rigid) of the device.

Other features and advantages of the invention will become apparent on reading the description, given by way of nonlimiting example and with reference to the appended drawings in which:
  • The figure 1 schematically illustrates the structure of a portable device not according to the invention according to a first embodiment with flexible means of the antenna;
  • The figure 2 schematically illustrates the structure of a portable device not according to the invention according to a second embodiment with retractable means of the antenna;

A la figure 1, un dispositif de communication radiofréquence non conforme à l'invention comprend un corps support de préhension 2a et une antenne 3; Dans l'exemple, ce dispositif comprend également un connecteur à contact 4, ici un connecteur de type USB; Toutefois, l'invention peut ne pas comporter de connecteur à contact électrique dans un mode de réalisation ou la communication radiofréquence est améliorée.To the figure 1 , a radiofrequency communication device not according to the invention comprises a gripping support body 2a and an antenna 3; In the example, this device also comprises a contact connector 4, here a USB type connector; However, the invention may not include an electrical contact connector in one embodiment or the radio frequency communication is improved.

Le dispositif comprend une certaine surface "S1" ou encombrement en vue de dessus (ou par exemple, en section transversale parallèle au plan d'un connecteur éventuel 4);The device comprises a certain surface "S1" or space in top view (or for example, in cross section parallel to the plane of a possible connector 4);

Le corps support de préhension 2a, ici une coque externe, comprend un circuit électronique 5a (non visible) qui s'étend à l'intérieur; Le cas échéant, le corps peut être directement une plaque de circuit imprimé (PCB) ou plaque support d'un circuit électronique quelconque.The gripping support body 2a, here an outer shell, comprises an electronic circuit 5a (not visible) which extends inside; Where appropriate, the body may be directly a printed circuit board (PCB) or support plate of any electronic circuit.

Le circuit peut comprendre notamment des pistes conductrices, des connexions et/ou des composants électroniques et/ou électriques tels qu'un bloc de connecteurs à lames élastiques ou autres. Comme on le verra plus loin, le dispositif peut comprendre des composants pour réaliser une fonction USB, une fonction radiofréquence, éventuellement disposés dans une carte distincte. Ces éléments de circuits sont susceptibles de perturber la communication radiofréquence établie à l'aide d'au moins une spire d'antenne radiofréquence 3 qui est disposée à proximité du circuit électronique.The circuit may include conductive tracks, connections and / or electronic and / or electrical components such as a block of connectors with elastic blades or other. As will be seen below, the device may comprise components for performing a USB function, a radiofrequency function, possibly arranged in a separate card. These circuit elements are capable of disturbing the radiofrequency communication established using at least one radiofrequency antenna turn 3 which is arranged close to the electronic circuit.

La spire d'antenne 3 définit une surface de couplage électromagnétique "S2" à l'intérieur de la spire.The antenna coil 3 defines an electromagnetic coupling surface "S2" inside the coil.

Selon d'autre mode de réalisation, l'antenne peut le cas échéant, être sous une forme différente de spires comme par exemple une antenne UHF.According to another embodiment, the antenna may, if necessary, be in a different form of turns such as for example a UHF antenna.

Conformément à une caractéristique de l'invention, l'antenne 3 présente au moins une portion de surface de couplage S2 qui est libre de tout circuit électronique et/ou pistes conductrices disposés directement en regard ou sensiblement en regard.According to a characteristic of the invention, the antenna 3 has at least a coupling surface portion S2 which is free of any electronic circuit and / or conductive tracks arranged directly facing or substantially facing.

Dans l'exemple, l'antenne est externe au corps rigide principal 2a; d'autre part, l'antenne est configurée sous forme d'une boucle tel un anneau de porte clés, s'étendant à l'arrière du dispositif. La boucle comprend les spires de l'antenne sans support et forme une armature circulaire en elle-même. La boucle est enrobée de préférence d'un matériau de protection et/ou renforcement mécanique des spires. Ce peut être un matériau élastomère ou plastique, notamment du caoutchouc.In the example, the antenna is external to the main rigid body 2a; on the other hand, the antenna is configured as a loop such as a key ring ring, extending to the rear of the device. The loop includes the turns of the antenna without support and forms a circular frame in itself. The loop is preferably coated with a protective material and / or mechanical reinforcement of the turns. It may be an elastomeric or plastic material, especially rubber.

L'antenne ainsi configurée a l'avantage de présenter une surface S2 qui est éloignée des perturbations du corps principal 2a.The antenna thus configured has the advantage of having a surface S2 which is remote from the disturbances of the main body 2a.

Cette boucle présente une élasticité apportée soit par l'enrobage ou gainage soit par le matériau des spires, par exemple en acier.This loop has an elasticity provided either by the coating or sheathing or by the material of the turns, for example steel.

De manière avantageuse, cette configuration permet d'accrocher ou saisir le dispositif. Quand il est en mode de connexion à contact, l'antenne possède plusieurs degrés de liberté: elle peut de ce fait être déplacée dans plusieurs directions et ne pas gêner ainsi une autre éventuelle connexion d'un autre dispositif à connecter sur un autre port d'ordinateur.Advantageously, this configuration allows to hang or grasp the device. When in contact mode, the antenna has several degrees of freedom: it can therefore be moved in several directions and thus not interfere with another possible connection of another device to connect to another port. 'computer.

Dans ce mode de réalisation, l'antenne 3c est disposée dans un couvercle 10c qui est articulé par rapport au corps du dispositif à l'aide d'une charnière 11.In this embodiment, the antenna 3c is disposed in a cover 10c which is articulated with respect to the body of the device by means of a hinge 11.

Le couvercle pourrait également être mobile différemment par rapport au circuit 5 interne dans le corps principale rigide 2c. Par exemple, le couvercle pourrait glisser par rapport au corps de manière à déporter l'antenne au moins en partie hors d'une surface en regard du circuit électronique contenu dans le corps.The cover could also be movable differently with respect to the internal circuit in the rigid main body 2c. For example, the cover could slide relative to the body so as to deport the antenna at least partly out of a surface facing the electronic circuit contained in the body.

En position déployée du couvercle figure 3b, l'antenne présente sa surface de couplage libre pour capter un champ électromagnétique dans la mesure où elle est déportée par rapport au corps principal. Dans cette position, la portée de communication est plus grande ou plus efficace.In the extended position of the lid figure 3b , the antenna has its free coupling surface to capture an electromagnetic field to the extent that it is offset from the main body. In this position, the communication range is larger or more efficient.

En position de connexion avec contacts électriques, le dispositif demeure fin, étroit en position déployé ou non sans gêner d'autres clés.In the connection position with electrical contacts, the device remains thin, narrow in deployed position or not without hindering other keys.

A la figure 4, le dispositif selon un mode de réalisation conforme à l'invention comporte des moyens amovibles permettant d'escamoter le corps 2f dit principal ou du moins le circuit électronique interne, celui-ci étant logé dans ou sur un capuchon ou tout autre élément rapporté.To the figure 4 , the device according to an embodiment according to the invention comprises removable means for retracting the body 2f said main or at least the internal electronic circuit, the latter being housed in or on a cap or other insert.

Le capuchon 10d présente une surface totale S1 qui est largement supérieure à celle du corps 2d; Lorsque le corps est fixé au capuchon ou support d'antenne 10d ou reçu à l'intérieur, l'antenne présente des portions S1 a et S1b qui ne sont pas directement en regard du corps et sont donc bien exposées au champ électromagnétique d'une borne externe de lecture. Un obturateur 40 ferme cet espace de réception 15.The cap 10d has a total area S1 which is much larger than that of the body 2d; When the body is fixed to the cap or antenna support 10d or received inside, the antenna has portions S1a and S1b which are not directly opposite the body and are therefore well exposed to the electromagnetic field of an external reading terminal. A shutter 40 closes this reception space 15.

Grâce à ces dispositions, le dispositif est pratique à emporter en un seul bloc dans sa configuration assemblée et à glisser dans un sac ou autre pour réaliser un contrôle d'accès.With these provisions, the device is convenient to carry in one block in its assembled configuration and slip into a bag or other to achieve access control.

La surface de couplage de l'antenne est calculée en fonction de l'encombrement du corps de manière à avoir la portée requise. En outre, lorsqu'il s'agit de se connecter à internet via un port d'ordinateur, il suffit d'extraire le corps 2d de l'étui 10d, ici une clé USB, pour retrouver un corps plus étroit ou fin et le connecter au port USB et réaliser une communication USB sans gêner d'autres connexions.The coupling surface of the antenna is calculated according to the bulk of the body so as to have the required range. In addition, when it comes to connect to the internet via a computer port, simply extract the body 2d of the case 10d, here a USB key, to find a narrower body or end and the connect to the USB port and perform USB communication without disturbing other connections.

Le cas échéant, différents capuchons de tailles et portées différentes peuvent être choisis selon le besoin de l'utilisateur, par exemple, selon le placement du dispositif sur lui, dans un sac et la manière de la présenter à un lecteur. L'invention permet donc du fait de la fonction amovible de l'antenne une personnalisation du dispositif radiofréquence au niveau de la portée.If necessary, different caps of different sizes and ranges can be chosen according to the user's need, for example, according to the placement of the device on him, in a bag and the manner of presenting it to a reader. The invention therefore makes it possible, because of the removable function of the antenna, a customization of the radiofrequency device at the level of the range.

Selon une caractéristique de l'invention, le dispositif comprend un connecteur USB (4) comportant des pistes Vbus (20) et GND (21) et les circuits de connexion 18a, 18b sont respectivement reliés à ces pistes.According to one characteristic of the invention, the device comprises a USB connector (4) comprising Vbus (20) and GND (21) tracks and the connection circuits 18a, 18b are respectively connected to these tracks.

La jonction au circuit électronique est ici matérialisée par des plots de connexion électriques 23, 24 d'un connecteur pour carte à puce 25. Dans l'exemple, le circuit RF est contenu dans une carte à puce 25, mais il pourrait être disposé dans le circuit électronique du corps support.The junction with the electronic circuit is here materialized by electrical connection pads 23, 24 of a chip card connector 25. In the example, the RF circuit is contained in a smart card 25, but it could be disposed in the electronic circuit of the support body.

Selon une autre caractéristique, le circuit de connexion 18a, 18b comporte deux capacités C1, C2 disposées chacune entre le circuit électronique / électrique 23, 24 et les points de connexion 20, 21 et un circuit de protection du circuit USB destinée à filtrer le signal RF superposé à Vbus.According to another characteristic, the connection circuit 18a, 18b comprises two capacitors C1, C2 each disposed between the electronic / electrical circuit 23, 24 and the connection points 20, 21 and a protection circuit of the USB circuit for filtering the signal RF superimposed on Vbus.

Le circuit USB comporte une protection par rapport aux signaux radiofréquence captés et véhiculés par l'antenne. Cette protection est ici une self de choc placée à l'entrée du circuit USB.The USB circuit has a protection against the radiofrequency signals picked up and conveyed by the antenna. This protection is here a shock choke placed at the input of the USB circuit.

Selon une caractéristique, l'antenne est logée dans un capuchon amovible 16 qui est apte à connecter les deux extrémités d'antenne aux pistes Vbus et GND respectivement.According to one characteristic, the antenna is housed in a removable cap 16 which is able to connect the two antenna ends to the Vbus and GND tracks respectively.

Le capuchon comprend donc des moyens de connexion au connecteur USB aptes à rentrer dans le connecteur et connecter les pistes Vbus et GND. Typiquement, le connecteur est un connecteur complémentaire USB dont deux pistes seulement sont reliées par l'antenne.The cap thus comprises means of connection to the USB connector able to enter the connector and connect the Vbus and GND tracks. Typically, the connector is a USB complementary connector of which only two tracks are connected by the antenna.

Le dispositif de l'invention dans sa version préférée constitue ou comprend une partie 26 réalisant une fonction de lecteur USB de carte à puce 25; Le circuit électronique de l'invention comprend le circuit du lecteur USB et un connecteur ISO 22 pour connecter la carte à puce 25, elle-même comportant un circuit électronique à interface duale ISO/ RF.The device of the invention in its preferred version constitutes or comprises a portion 26 performing a USB smart card reader function 25; The electronic circuit of the invention comprises the circuit of the USB reader and an ISO connector 22 for connecting the smart card 25, itself comprising an electronic circuit with dual ISO / RF interface.

Selon une caractéristique, l'antenne comprend un indicateur de présence de champ disposé dans le capuchon (non représenté).

This indicator can be for example a vibrator or a sound or light indicator. For example, a circuit comprising one or more LEDs can be placed on the antenna circuit so as to produce a light effect that can be customized to the user's choice (pattern, color, etc.)

L'utilisateur peut ainsi être amené à utiliser entre plusieurs capuchons à indicateur celui qui produira l'indicateur selon l'usage considéré.The user can thus be made to use between several indicator caps the one that will produce the indicator according to the use in question.

Selon une autre variante de réalisation, le capuchon de la figure 5, peut le cas échéant être fixé à l'arrière du dispositif sur des points de connexion spécifiquement préparés à cet effet. Par exemple, UN PCB de la clé peut avoir des pistes de connexion se prolongeant vers l'arrière et accessibles à travers une fente ménagée dans la coque.According to another variant embodiment, the cap of the figure 5 can, if necessary, be attached to the rear of the device at connection points specifically prepared for this purpose. For example, a PCB of the key may have connection tracks extending rearward and accessible through a slot in the shell.

De son côté, le capuchon peut comprendre une portion plate en excroissance correspondant à la fente et portant les pistes de l'antenne. Cette excroissance une fois introduite dans la fente provoque le contact ohmique de l'antenne avec les pistes de connexion au circuit électronique et /ou RF.For its part, the cap may comprise a flat portion protruding corresponding to the slot and carrying the tracks of the antenna. This protrusion once introduced into the slot causes the ohmic contact of the antenna with the connection tracks to the electronic circuit and / or RF.
