Definitions

  • the invention relates to a transponder according to the preamble of claim 1.
  • a transponder is already known from DE 39 35 364 Cl.
  • Transponders usually consist of a transmit / receive module and transmit and receive antennas connected to it.
  • the transponders are used as so-called radio tags (e.g. for anti-theft systems in department stores or for luggage detection and distribution systems at airports and train stations) by attaching them to the objects to be monitored or recorded (sales goods, luggage, etc. ) are attached and given a specific coding, which - in the case of theft protection systems in the event of theft or in the case of luggage distribution systems at certain stations in the distribution system - enter into an active connection with transmitting / receiving devices and exchange data by radio (including the coding stored in the transponder).
  • Radio tags are often implemented - similar to a conventional luggage tag - in the form of a paper or plastic film carrier on which the radio-technical components (in this case the transmission antenna, reception antenna, transmission / reception module) are applied.
  • the radio-technical components in this case the transmission antenna, reception antenna, transmission / reception module
  • Radio tags have already been proposed which are equipped with wire coils as the transmitting and receiving antenna and which are connected to a transmitting / receiving module in the form of an integrated circuit.
  • both wire coil antennas and the integrated circuit are arranged on a common carrier. Transmitting and receiving frequencies are different from each other.
  • a radio tag with an antenna and a transmission / reception module implemented as an integrated circuit, in which the antenna is arranged as a coil-shaped planar conductor structure on both sides of a film.
  • This type of radio tags is expensive to manufacture due to the film body to be processed on both sides and requires one or more vias through the film body in order to also be able to connect the two antenna parts or the transmitter / receiver module to the antenna part arranged on the other film side.
  • so-called contact chip smart cards in which the bidirectional data exchange and the energy supply of the cards take place via a contact field as soon as the card is inserted into an assigned reader / writer (cf., for example: G. Roethenbaugh: "Technology overview: The smart card continues to grow "; in: Automatic ID News Europe (June 1996), pages 19 to 20).
  • a transponder is also known from the above-mentioned DE 39 35 364 Cl, in which the bidirectional data exchange and the power supply of the circuit can take place either via a radio link or via a contact field with a single integrated circuit.
  • the transponder has a contact field as well as a transmitting and a receiving antenna.
  • a switch can be used to connect either the switch panel or the two antennas to a shared transmit / receive circuit with memory.
  • the transmission and reception frequency are different in this solution.
  • Switch, transmitter / receiver circuit and memory are implemented in the form of a single integrated circuit on the top of a carrier body, on which the contact field and the two antennas are also located.
  • ASIC Application Specific Xntegrated Circuit
  • the main advantage of the invention can be seen in the fact that with the functional separation of the overall transmission / reception circuit into a first transmission / reception circuit for the radio connection and a second transmission / reception circuit for the contact connection on the one hand and the use of a common memory for the two separate ones and independently operable transmission / reception circuits of the transponders can be manufactured more cost-effectively overall, since standard ASICs can be used, which can be produced more cost-effectively due to their large numbers.
  • Another advantage is that the two types of transmission can be operated in parallel;
  • Transponder can e.g. Send via the radio link and receive via the contact field at the same time (or vice versa).
  • the invention is explained in more detail below with reference to a preferred exemplary embodiment shown in the single figure.
  • the figure shows a transponder in plan view, in which the bidirectional data exchange with a read / write device (not shown) can take place both via a radio connection and via a contact connection.
  • the transponder is implemented in the form of a so-called radio tag, in which the first transmission / reception circuit 3, intended for the radio connection, of an overall transmission / reception circuit, together with the associated transmission antenna 4, are integrated on a common film 5.
  • the first transmit / receive circuit 3 is also connected to a separate receive antenna 2.
  • the receiving antenna 2 and film 5 with the transmitting antenna 4 and the first transmitting / receiving circuit 3 of the overall transmitting / receiving circuit are arranged on one side of a flexible, flexible carrier 1.
  • the transmit / receive circuit 6 is shown as it would be seen when looking at the back of the carrier 1.
  • Both circuit parts 3, 6 of the overall transmission / reception circuit access a shared memory during their operation, which is likewise arranged on the same side of the carrier 1 as the transmission / reception circuit 3 and in which, inter alia, the coding is saved.
  • the bidirectional data exchange and the supply of energy via radio connection is carried out via the transmitting antenna 4 and receiving antenna 2 and the transmitting / receiving circuit 3, the transmitting and receiving frequencies and the types of modulation used for the transmitting and receiving case being different from one another (for example transmission on 132 KHz (FSK modulation), reception in the range 2 - 4 MHz (PSK modulation)).
  • the transmitting and receiving frequencies and the types of modulation used for the transmitting and receiving case being different from one another (for example transmission on 132 KHz (FSK modulation), reception in the range 2 - 4 MHz (PSK modulation)).
  • the bidirectional data exchange and the supply of energy via a contact connection is carried out via the transmitting / receiving circuit 6, which comes into direct contact with the corresponding contact field of the read / write device (not shown) with its contact field.

Abstract

L'invention concerne un transpondeur dans lequel l'échange bidirectionnel de données avec une unité externe d'émission/de réception et l'alimentation en énergie dudit transpondeur peuvent s'effectuer par l'intermédiaire d'une liaison radio ou d'une liaison par contact. Pour la liaison radio, il est prévu une antenne émettrice et une antenne réceptrice séparée appropriée, la fréquence d'émission et la fréquence de réception étant différentes. Pour la liaison par contact, il est prévu un banc de contacts, et l'antenne émettrice et l'antenne réceptrice, ainsi que le banc de contacts sont reliés par l'intermédiaire d'un circuit global intégré d'émission/de réception, à une mémoire utilisée en commun pour l'échange bidirectionnel de données. Afin que ce transpondeur soit aussi économique que possible à produire, il est prévu selon l'invention, que le circuit global intégré d'émission/de réception comprenne un premier circuit d'émission/de réception connecté à l'antenne émettrice et à l'antenne réceptrice, ainsi qu'un second circuit d'émission/de réception connecté au banc de contacts. Il est également prévu que les deux circuits d'émission/de réception puissent être actionnés indépendamment l'un de l'autre.
