    description
    The present invention relates to a short-range electromagnetic local area network communication antenna for mobile, personal devices such as cellular phones, smart phones, PDAs, or E-Rcadcr via RF1D, NFC, or the like, having an inner antenna, an intermediate antenna without contact with the inner antenna, and one with the intermediate antenna connected, outwardly communicating outdoor antenna.
    Antenna arrangements of this type are known, for example, from WO 2007/080214 A1 and allow a range increase for spatially limited indoor antennas for electromagnetic short-range communication. The range is primarily dependent on the dimensions of the antenna, since the Indduktionsleislung a smaller antenna is relatively low. In cases where the indoor antenna is integrated into a chip inserted into the mobile device, such as an SMS module, the antenna arrangement of WO 2007/080214 A1 can be used to increase the range because of the (relatively large) external antenna from that for the electromagnetic
    A large amount of energy can be absorbed in the near field communication provided by the electromagnetic field and transmitted to the small inner antenna without contact via the intermediate antenna. A disadvantage of the prior art is the complex integration of the intermediate and outer antenna in the housing of the mobile device, wherein the optimal arrangement of the intermediate antenna in the immediate vicinity of the inner antenna (for example directly on the SIM card) is often not easy to achieve. because other components, such as the battery or the chip pads, claim this area.
    These and other disadvantages of the prior art are achieved by an antenna arrangement of the type mentioned, in which the intermediate antenna and the outer antenna are applied or integrated on two opposite side surfaces of a preferably replaceable battery, wherein the intermediate antenna in inserted into the mobile device battery in the communication area the indoor antenna is angeordnel. As a result, an optimal power gain can be realized with minimal effort. A modification of housing parts or other components -1 - N0011271 / Wp
    of the mobile device is avoided. Also, the battery can remain essentially structurally, since it is supplemented only on its outside by a flat antenna arrangements. Advantageously, in this case, the inner antenna in a einleekbare in a receptacle of the mobile, personal device smart card, e.g. a SIM card, integrated. 5 The properties of electromagnetic short-range communication, for example the RFID identifier, are thus device-independent and linked to the chip card.
    A further advantageous embodiment of the invention can provide that the inner antenna is part of the contact arrangement of the Chipkartc. As a result, a cost-effective production of the inner antenna is guaranteed. In a further advantageous embodiment of the invention, the inner antenna can be arranged on the surface of the chip card facing towards the intermediate antenna. This minimizes the distance between the intermediate and the inner antenna.
    Furthermore, in an advantageous manner parallel to the outer antenna, a non-contact with this communicating, reinforcing housing antenna can be arranged. This further increases the achievable communication range because the entire outer surface of the housing can be used for the antenna.
    In a further advantageous embodiment of the invention, the intermediate antenna and the outer antenna and their connecting lines can be integrated into a label applied to the battery. This minimizes the cost of manufacturing because it can use conventional batteries that use only a different label.
    In doing so, advantageously the label may comprise an absorption-inhibiting material, e.g. Ferrite, exhibit. This shields induction absorbing battery oil components. In an advantageous manner, an optical identification can be provided on an outer side of the housing of a mobile, personal device having the antenna arrangement according to the invention, optionally on a sticker. The optical identification enables a visual check of the data transmitted via the electromagnetic short-range communication and thus extends the functionality and enhances the security of short-range communication.
    A further embodiment of the mobile, personal device according to the invention may provide that the optical identification comprises an image, personal data, personal characteristics, biometric features, an identification number, an address and / or a -2- N0011271 / Wp
    Telephone number of the user includes. As a result, the assignment of the RFID data to a specific person can be checked, whereby misuse can be prevented.
    In a further advantageous embodiment of the invention, the optical identification may be a laser engraving. As a result, a high degree of protection against forgery can be achieved for optical identification.
    Particular features of the invention will now be explained in detail with reference to an exemplary embodiment with reference to the accompanying drawings, wherein Fig. 1 shows a schematic cross section through the antenna arrangement according to the invention.
    The cross section shown in Fig. I is highly schematic and explains the arrangement and the interaction of the individual elements of the invention, wherein the proportions shown do not have to correspond to the actual embodiment of the invention. Depending on the design of the mobile device in which the antenna assembly is installed, the respective configuration can vary widely, with a person skilled in the art can adapt the invention to various mobile devices, such as different existing or redesigned Mobilfunkc without this being inventive to have to.
    Hereinafter, in the context of this description, the mobile device is also referred to as a mobile phone for the sake of simplicity, and the invention is not limited thereto and also with other mobile devices, such as a smartphone, a radio, a Tablet PC. or a similar device can be used advantageously.
    Due to its size, the rechargeable battery 4 shown in FIG. 1 usually occupies a substantial part of the space available in the device housing of a mobile telephone. Since the battery 4 usually has a shorter life than the mobile device itself, it is usually carried out interchangeable. For example, the battery 4 is inserted in many devices in a receptacle on the rear of the device, which is closed by a housing cover 13. The connection between the battery 4 and the remaining electronic components 11 of the mobile device are generally produced by means of touch contacts.
    As in the dargestcllten embodiment, a receptacle for a smart card 8, in particular a SIM card is provided in most mobile phones below the battery 4. On the chip card 8, among other things, all personal or contract-related data are stored, which allow the respective network operator to allocate and clear the communication services. This makes it possible, as is well known. -3- N0011271 / Wp # »· · #s» * to use different mobile phones or mobile devices with the same chip card, or simply switch to another device. Hs is only required to remove the SIM card from the old device and insert it into the new device. The invention is not limited only to SIM cards, but can be implemented with all smart cards that provide 5 corresponding functionality. For example, the smart card could be a memory card provided with an RFID antenna, such as a micro SD card, on which all relevant personal or contractual data and any programs (e.g., cryptographic programs) executable on the mobile device are stored.
    Integrated into the chip card 8 is an interior antenna 1 for electromagnetic proximity communication, which can also be used without its own power supply. Such antennas are known as RFID antennas, although other standards such as NFC or the like may be used. The inner antenna can be integrated into the contact arrangement of the chip card, as is already known in the prior art. In this case, unused free contacts are connected to the RFID antenna or formed enlarged to antenna size of the SIM card. The contacts are connected inside the card with an electronics chip on which the RFID applet (separate from the functionality of the SIM card) is running.
    The contact arrangement of the Chipkartc 8 touches when properly inserted into the device Chipkartc 8 corresponding contacts 12 of the mobile device through which a connection with the remaining electronic components 11 of the mobile device is made, this results (as shown in FIG. 1) usually an arrangement in which the RFID antenna (inner antenna 1) of the chip card 8 between the Elektronikkomponcnten 11 of the mobile device on one side and the chip card 8, the battery 4 and the Gchäusedeckel 13 is installed on the other side and by this electromagnetically 25th is shielded. This causes a shortening of the antenna range, which is undesirable. Moreover, the space on the chip card 8 is very limited in space, so that only a relatively small RFID antenna can be provided, which in turn adversely affects its range. As is known, the achievable range of an RFID antenna is directly proportional to the areal extent of the antenna. The size of the antenna can be extended to a maximum of the size of the chip card 8, whereby a further internal antenna 9 can also be provided, which can be located on the side of the chip cold opposite the contacts 12. However, this antenna (which need not be provided according to the invention) is limited in its size to the dimensions of the chip card 8.
    In order to increase the range of the antenna (s), according to the invention an intermediate antenna 2 is provided on the side surface of the battery 4 facing the chip card 8, which antenna 5 is arranged substantially parallel to the inner antenna 1 or 2 and communicates with it without contact. The Zwischenantennc 2 is connected via connecting lines 5 with an outer antenna 3, which is arranged on the outwardly directed side surface of the battery 4. This external antenna 3 can thus extend substantially over the entire surface of the battery outer side and thereby also receive a weaker RFID-10 signal and pass it on to the inner antenna. The principle of this antenna amplification is known to the person skilled in the art from the prior art and is described in detail, for example, in WO 2007/080214.
    The intermediate antenna 2 and the outer antenna 3 are integrated in a label 6, which is glued to the battery 4. The thickness of the label 6 is exaggerated in FIG. In fact, the thickness of the label 6 with the antennas 2 and 3 arranged therein differs only insignificantly or not at all from the labels conventionally used for the wrapping of rechargeable batteries. Thus, the implementation of the invention in the design of the corresponding devices requires no complex consideration. Also, the invention can be advantageously used in existing devices by simply replacing the old battery with a new one or also supplemented by a corresponding label 6.
    It is further advantageous that the external antenna 3 is arranged directly below the housing cover 13, which shields the antenna only insignificantly. The Elektronikkompcnten 11 and the battery 4 impede the RFID communication ion only to a small extent. In addition, to shield induction absorbing components of the battery, label-absorbing materials such as ferrite may be provided in the label 625.
    In the illustrated embodiment, a further antenna, the housing antenna 10, is arranged in the housing cover 13. The housing antenna 10 is galvanically isolated from the external antenna 3 and communicates with it without contact. As a result, the antenna area c relevant for the range of the antenna arrangement can be further increased. The housing antenna 10 can either be integrated into the Gehauscdeckel 13 or be applied to the outside or inside thereof, for example by means of a label. -5-
    N00ll271 / Wp For safety-critical applications, such as payment functions or entry control systems. in which an identification of the owner of the mobile device takes place without contact via the RFID applet of the chip card, the security can be considerably increased by an optical identification is attached to the housing of the mobile device. The optical identification may be a simple label on which an image, personal data, personal characteristics, biometric features, an identification number, an address and / or a telephone number of the user is printed. The optical identification makes it possible to re-examine the owner of the mobile device, who identifies himself via the RFID functionality, in order to prevent misuse by third parties. To complicate the counterfeiting of the label, the label may be provided with falsifiable features such as laser engraving. Often it is sufficient in this case, if the forgery of the optical identification is delayed only relatively short, since the loss of about a mobile phone usually very quickly noticed, and the corresponding Auswcisfunktionalitäten can be locked before the fake label manufactures hergcstellt and abuse is possible.
    Alternatively, the optical identification can be provided without a label directly on the housing of the mobile device, preferably on the housing cover of the mobile device, for example by means of a laser (engraving).
