Definitions
- Device and system for detecting the passage of objects, persons or animals carrying an RFID tag, in the order of passage and application to the detection of baggage are known.

- the invention also relates to the application of the device according to the invention to the identification of objects equipped with RFID tags, transported on a conveyor.
- the aforementioned objects are luggage transported to a gantry or tunnel.
- gantries or tunnels are equipped with rigid and fixed antennas, connected to an RFID reader that allows remote reading labels fixed or glued on the luggage, thus allowing to identify them.
- the object that is to say the luggage, may escape reading and not be identified.
- UHF labels are sensitive to the environment. They are designed to work with a known dielectric: paper or plastic tape support. They must work without any contact with other materials.
- the RFID reader will receive an offset signal in frequency and a lower amplitude level.
- the offset of the tuning frequency can cause detection. the second object before the first. This situation is further complicated when the number of objects is important and these objects follow each other closely.
- the object of the present invention is to overcome the above disadvantages.
- Another object of the invention is to provide a device and a system for performing the detection of objects, people or animals in an orderly manner with respect to their order of passage.

- RFID Radio Frequency IDentification
- the second object when first and second objects or others follow each other, the second object, further from the first support carrying the detection antenna with respect to the first object, is at least partially isolated from the electromagnetic waves by the second support mobile which attenuates the passage of electromagnetic waves to this second object. Electromagnetic waves being attenuated at the level of second object the first object is detected before the second object despite the difference in sensitivity that may exist between the radio frequency identification tags carried by the first object and the second object.
- the conditions for reading the labels of the objects are thus significantly improved with respect to known devices and an orderly reading of the objects during their passage is made possible by the device according to the invention.
- At least a third mobile support forming, at rest, a barrier or a curtain with respect to the passage of objects, and which, in contact with the latter, is likely to move towards a position erased, is disposed upstream of the second movable support and attenuates the passage of electromagnetic waves in the opposite direction to the passage of objects.
- the attenuation of electromagnetic waves passing to the objects following the object whose label is read is more important.
- At least a fourth mobile support forming, at rest, a barrier or a curtain with respect to the passage of objects, and which, in contact with the latter, is likely to move to an erased position, is disposed downstream of the first movable support and attenuating the passage of electromagnetic waves.

- the waves used are electromagnetic waves with a frequency of between 865.6 and 867.6 MHz, the wavelength is about thirty cm.
- the distance between the supports is in this case around 34 cm, for example between 29 and 39 cm.
- the various mobile supports are spaced apart in the direction of movement of the objects by a distance of between 2.5 and 3 times the wavelength of the electromagnetic waves used for the detection.

- the antenna is disposed substantially vertically with respect to the plane of passage of objects, persons or animals. Tests have shown, in fact, that an arrangement of the antenna substantially vertically with respect to the plane of passage of the objects gives a better detection of the objects during their passage.

- the fabric according to the invention may further comprise, on the face opposite to that coming into contact, a conductive layer fixed integrally to the adhering layer and connected to the ground of the device, when the support is a support chosen from the second, third or fourth support.
- This conductive layer is an adhesive conductive metal layer providing attenuation of the electric waves.
- This conductive layer is generally of the type used in shielding applications of electrical equipment to be EMC (Electro-Magnetic Compatibility). Therefore, the use of this conductive layer for this application is well justified since we want to attenuate and / or prevent the propagation of electromagnetic waves.
