- the lateral transmission bands are generated by any transponder subjected to a magnetic interrogation field that the transponder modulates, notably in amplitude, during its response.
- an amplitude modulation of a sinusoidal signal of frequency 13.56 MHZ by a modulating signal of 847Khz corresponding to the subcarrier, generated by the transponder creates a spectral point of view a signal at two sidebands at 13.56MHz +/- 847 KHz, respectively 12.71 and 14.4 MHz.
- the resonance frequency of the passive resonant circuit is chosen at 14.4 MHz. ie 13.56 MHz + 847 KHz.
- At least one transponder antenna format F and a transponder response having a behavior or characteristics corresponding to this format are determined and then the passive resonant circuit is configured so as to obtain the behavior or the characteristics corresponding to this format for each transponder.
- the passive antenna has been deliberately delimited in a zone Z (FIG 6) between two rectangles 25, 26 centered on one another and on the ID1 format described in ISO / IEC 14443, respectively 81 mm x 49 mm and 64 mm x 34 mm

- This travel document thus produced will be able to accommodate one or more transponders 13- 16 each taking the local field portion induced by the passive resonant circuit subjected to the reader's field added by the field radiated by the reader's antenna around the surface.
- the antenna module (s)
- Figures 8 and 9 illustrate the travel document reading system. It comprises, as before, a reading medium 19 containing a transmitting and receiving antenna 18 connected to means 28 for processing and operating the received signals.
- the resonant circuit 17 is fixed here under the reading medium.
- the advantage is to have a common circuit at the reader level for all passports. While in the example of Figure 7, each document containing the resonant circuit, it is not essential to have it at the reader.
- the magnetic field amplitude H of the reader is set to a value greater than or equal to at 1, 5 A / m, and the response amplitude of the transponder to a value greater than or equal to 30 / H 1 ' 2 .
- the travel document includes a large format transponder 3 for example ID1 and several transponders 13-16 as electronic visas of reduced formats.
- the antenna modules 13-16 are not necessarily located on the same plane as that on which the passive antenna is located.
- the passive resonant circuit 17 is arranged outside the travel document. It is associated with the reading system by being fixed below the reading medium.

- the transponders to be read (13-16, 3) are in the travel document 27B.
- the geometric and electrical characteristics of the passive resonant circuit and of the antenna modules preferably correspond to the following description: Seen from the reader but also test devices, such as those described in the test methods of contactless products: ISO / IEC 10373-6, the travel document containing several Electronic Visas must appear as a single product without contact.

- the charge induced by the transponder corresponds to an ID1 antenna tuned to 13.56 MHz with a resistive portion of 1.8 k ⁇ and whose voltage resulting from the interrogation field is less than 6V continuous across the load.
- the passive antenna has therefore been deliberately delimited in a zone Z between two rectangles 25, 26 centered on one another and on the ID1 format described in ISO / IEC 14443, respectively 81 mm x 49 mm and 64 mm x 34 mm (Fig. 6)

- the optimum coefficient of quality of this resonant circuit to fulfill the conditions described above is between 10 and 20.
- the optimum value of the quality factor of the passive resonant circuit is 20. This allows antenna design technologies with high electrical resistance such as the silkscreen with silver ink or carbon ink. Due to the need for an overvoltage factor, the passive resonant circuit must consist of an antenna consisting of several turns and connected to a capacitor.
- the passive resonant circuit must provide the electromagnetically coupled antenna modules with the additional energy they need because of their low coupling surface with the reader.
- the passive resonant circuit must generate an additional local field to that from the reader which allows the feeding of the antenna modules.
- the transponder 13 can be implemented in the form of an antenna module that complies with the smart card technology. It comprises a flat antenna 29 on an insulating support 30 (dielectric film) in a plane and connected to an integrated circuit chip 31.
- the chip may or may not include a protective coating resin 32.
- the assembly may have a thickness overall less than 1 mm.

- the transponder will advantageously be of a reasonable size, for example: length 25 mm by width 15 mm and having an antenna of about fifteen turns for example between 13 and 18 turns. The number of turns will depend very slightly on the chosen chip.
- Each turn for example copper, has, for example, a width of the order of 50 to 300 microns with a spacing between two contiguous turns of the order of 50 to 200 microns.
- An antenna module of surface too small for example less than 10mm by 10mm would require a very precise positioning with respect to the passive resonant circuit to allow a good functioning which excludes a priori the achievements based on antennas realized directly on the surface of the chip.
- an antenna module larger than 30 mm by 30 mm would consume too much magnetic field and would couple too much with others antenna modules to enable the operation of several integrated circuit chips or electronic visas.
- the resonance frequency of the transponders is 17 MHz.
- the number of revolutions of the passive resonant circuit is optimal for 4 turns.
- the surface area of the capacitor plates is calculated to perform the aforementioned frequency tuning.

- 2 resonant frequency resulting from the association of two transponders with the same resonance frequency "fres”.
- the passive resonant circuit is tuned so that the resonance frequency resulting from the association M corresponds to one of the frequencies of the lateral transmission bands of the transponder to be read.
- the two associated elements may be grouped together in the same medium, for example a 6A travel document cover.
- each electronic visa is disposed in a support 33, 34, for example a sheet substantially in document format or slightly lower.
- support is in ID1 format or slightly lower. The important thing is not to leave any choice to the user when fixing or sliding in the document.
- This transponder support 33 is to slide in the document or to stick on a page, in particular with a self-adhesive coating.
- the transponder 13 is placed in a random position inside the support during the manufacture of the visa, in particular by lamination. In FIG. 12, it is disposed along the left lateral edge 35 while it is disposed along the right lateral edge 36 in FIG. 13. Thus, during a superposition of the two sheets, the transponders couple less together.
- a method for producing the transponders must comprise a step and means for random or varied arrangement of the transponder in a transponder support sheet surface, for example, during the lamination of sheets taking the transponder in sandwich form.
- the reading method may implement an anticollision mechanism or protocol of known type including that described in the standard.
- the mechanism can be triggered on the initiative of the reader processing means.
- the invention viewed in another aspect, allows the realization of electronic travel document.
- This document is intended to include a plurality of transponders conforming to particular normative constraints or specifications (ICAO), which impose at least one transponder antenna ID1 format, a minimum reading magnetic field amplitude H and a minimum response amplitude of the transponder antenna. transponders.
