The present invention relates to the field of identification, stationary or moving objects, is for them to discover and identify the object, attached to this label. The device can be used for identification and authorization of people in certain areas, work stations or terminals of the communication and information systems, search and identification of animals, labeling of biological samples, chemicals and medical instruments, automated security systems, electronic payment systems and other systems.

A known design of a high-frequency identification devices (labels) mounted on a flexible Board. The device transmitting in response to the request polling signal with the identification information contains a flexible charge placed on it IP encoder for recording identification information, the antenna and the generator, the transmitting antenna modulated with the identification information of the RF signal. The device can be made by building on a flexible substrate, such as plastic, printed circuit conductors using conductive ink based on graphite or silver [1]. The device may be made in the form of a bracelet and serve to pass into the protected premises. The disadvantage of these devices are quite large dimensions and neobhodimom case, the range of the strong connection between the poll system and device are greatly reduced.

The closest to the technical nature of the present device is a high-frequency identification scheme, designed for installation in device recognition (identification) of interest. The schema contains a polymer substrate, on both sides of which methods technology of printed circuit boards formed or integrally connected with her items, using the resistance of the substrate as a component of such elements [2]. The disadvantage of the proposed technical solutions are difficulties associated with the possible use of circuit devices that do not have the planar structure, since the presence of elements on both sides of the substrate prevents inlining, for example, in small-volume products such as labels, buttons, cylindrical objects of small diameter. In addition, the use of conductivity of the substrate leads to the necessity of taking measures to avoid the appearance of spurious relationships between the individual circuit elements in the device.

The basis of the invention is the construction of an identification device devoid of the above disadvantages, and which allows to significantly extend the scope of such is Imperator, to have small dimensions and weight, reproducible with high accuracy settings and to provide the communication range of at least 50 meters

The solution of this problem is achieved by the fact that the device identification containing a frameless IC for recording and issuing identification information, the inductor and capacitor that form the antenna for bidirectional contactless communication with the poll system, and circuit Board, the card is made of polyimide tape with one-sided metallization. The use of polyimide allows you to extend the operating temperature range of the device. From the layer of metallization methods of thin-film photolithography to form the patch (connective) track parallel to the edges of the ribbon. After mounting on the ribbon of the remaining elements of the device it is folded several times so that the areas remain parallel, and glue them together. To prevent unwanted contacts separate areas of the switching paths covered with a protective layer, such as photoresist. To prevent exfoliation of the conductors of the radius of bend of the tape shall not be less than the thickness of the conductors, and the thickness of the adhesive connection lies at the limit of the C which interval switching tracks on different sites can be connected via additional capacitors, creating custom inductive elements. In addition, created on different tracks electrodes extending from them to the other side of the tracks, but not connected with it is overlapping on different parts of the form and accumulate electric charges of the capacitors, which are used to power the IC. To this end the structure of the device can be a diode for charging these capacitors induced in the antenna by a high-frequency voltage. This significantly reduced the size of the finished device, eliminating the need for connection of the switching paths through the through-plated holes in the circuit Board and there is a possibility of complications, functional scheme of the device without the introduction of additional physical elements.

The design of the proposed device can be illustrated by the following examples.

Example 1. The layout of the identification device was assembled on a flexible mounting strip of polyimide film coated with a layer of aluminium of a thickness of 10 μm. Conductive switching paths were generated with a resolution of thin-film lithography (width 50 μm). The length of the tracks, and hence the size of the segment is here tracks amounted to 1,015 µh, but the dimensions of the circuit Board in the folded state of 2.5×1.5 mm For bonding layers was used organosilicon compound.

Example 2. Similar to that specified in example 1 was made of polyimide circuit Board with dimensions of 2.5×3,5 mm. On Board was mounted open frame IP, then the card was folded, the edges are glued together and it is placed inside a wire coil with an inner diameter of 2 mm Obtained the world were tested as part of the identification system, operating at a frequency of 150 kHz. The detection range was 62 meters

Using the proposed design of an identification device in comparison with the prototype provides a reduction in size, extends the operating temperature range, allows you to use when making group methods of microelectronic technologies and thus reduce complexity. Due to this expands the scope of application of such identification devices.
