Description

Multiple information carrier

The invention relates to dipole antennas and a method for their production, as well as reversals of such antennas.

Information carriers or data carriers which serve to store data / information are described in the prior art. The information on the carriers are preferably read out by means of capacitive readers. Disadvantages of the reading devices or apparatuses disclosed in the prior art are that separate, capacitive reading devices must always be available for the individual applications and these are often connected via an interface to data-processing media. The spread and acceptance of the readers is relatively poor and associated with additional costs by the purchase of the readers. In addition, the linkage of real printed information with digital information is very difficult to achieve. One possibility is barcodes, which can be captured by suitable scanners or cameras and can call up digital content. A disadvantage of the known barcodes is that they are associated with the system typical handicaps and z. B. Information can be copied as often as you like, optically occupy space on products or advertising media, poorly individualized in sufficiently good quality, it requires a direct visual connection between code and detection unit, which by dirt, scratches, lighting conditions, etc. a correct detection and reading complicate the information or prevent it completely. Previous known capacitive data carriers always bridge between (at least) one reading and one receiving electrode within a reading device. Depending on the presence or absence of a capacitive structure, a logical "1" or "0" is detected. The prior art shows several possibilities for producing information carriers or data carriers by means of printing techniques or other coating methods, which information carriers or data carriers can be read out by means of a suitable reading method or reading device (eg US 3,719,804). Probably the most widely used information carriers produced in this way are barcodes in the embodiment as a one-dimensional bar code or for example as a two-dimensional variant. These are recorded with suitable optical scanners and optionally further processed via corresponding data processing systems.

Furthermore, EP 1 803 562 describes a process for the transfer of imaging layers from a carrier foil or transfer foil to printed sheets in a sheet-fed process. bordering machine. In this case, an adhesive is applied in a first application unit and moved together in a further coating unit with a transfer film and applied material from the transfer sheet by adhering to the sheet. In this case, a transfer nip is formed in the coating unit and the transfer film is placed on the surface of a press roller along with the transfer-coated side on a printed sheet and passed under pressure together with this through the transfer nip, so that the imaging layers provided in adhesive areas of the carrier film be transferred adhering to the sheet. This can be easily applied barcodes and alphanumeric information. In addition, DE 10 2008 013 509 A1 describes a steganographic method whereby security features in printed products can be generated by means of transfer ribbon technology. The verification of the features is done optically by means of decoder.

DE 10 2006 031 795 A1 discloses a security feature which has been produced by means of transfer film technology. In this method, resistors or Wderstandsnetz- works are introduced into printed products, which should represent a security feature. The verification is done contact-based by means of a reader, through which the resistors are measured according to the ohmic principle.

The document DE 10 2004 007 458 A1 describes a method for the production of RFID tags and the document DE 10 2004 019 412 A1 describes a method for printing electrical and / or electronic structures and foil for use in such a method. Both documents mention the possibility of using sheetfed and / or web offset presses for producing electrically conductive structures.

Document DE 10 2007 026 720 A1 discloses a method and means for producing self-adhesive RFID antennas and methods for their production. Therein, inter alia, the use of an aluminum foil in a thickness of 1-20μηι described which are punched in a special machine with the aid of tools (punching) from a web-shaped carrier and de-latticed.

In addition, DE 10 2005 042 444 B4 describes an arrangement for an RFID transponder antenna consisting of two galvanically decoupled structures. On the one hand, an impedance-adapting structure and, on the other, a resonant structure, which can be fabricated on different substrates to ensure particularly efficient production. Known manufacturing methods are conventional methods such as printing, etching and laying techniques, as they are state of the art for RFID antennas. The antenna is immediately ready to receive the RFI D chip by means of adhesive or soldering techniques and thus represents a complete RFI D antenna with transponder chip. This has several disadvantages especially in the application of the chips, because the relatively large resonance-adapting structures, the actual dipole antennas, run through the placement machines and reduce their speed.

A disadvantage of the carriers disclosed in the prior art is that they can only be read by a special reading device or apparatus. In addition, no support is described that is interpretable by different readers or apparatus.

The object of the invention is to provide a simple and economically producible carrier for storage of information / data, which does not have the disadvantages of the carrier described in the prior art.

The problem is solved by the independent claims. Advantageous embodiments will be apparent from the dependent claims.

It was completely surprising that a multiple information carrier comprising at least one electrically conductive layer and an electrically non-conductive substrate can be provided, wherein at least one first electrically conductive layer as a touch structure and a second electrically conductive layer as an antenna on the substrate regions , The information carrier or a group of information carriers can preferably be used as a multiply readable information carrier, whereby the information carrier and the group of information carriers can be interpreted by different technologies and thus used universally. It may be advantageous if the first and second layer of the information carrier is read out together or separately. It was completely surprising that an information carrier is provided which is used so that both layers, the touch structure and the antenna can be read out with a readout method. This may be, for example, a device having an area sensor. Furthermore, it may be preferable for the first and second layers to contain identical or unequal information.

For the purposes of the invention, an information carrier is in particular a medium for storing, mapping, storing and / or associating information. In the context of the invention, an antenna designates in particular a device or a device for transmitting and / or receiving electromagnetic waves. Accordingly, an information carrier is provided which, for example, can store information and, for another, functions as an antenna. According to a preferred embodiment of the invention, at least one electrically conductive layer is arranged as a touch structure on an electrically nonconductive substrate and preferably comprises a touch point, a coupling surface and / or a conductor track.

In the sense of the invention, a coupling surface is in particular an electrically conductive region on the substrate. The coupling surface represents a preferred variant of the information carrier, which makes it possible, for example, to couple external electrical capacitances, which are not part of the touch structure, and thus to increase the effective electrical capacitance of the touch structure of the information carrier. As a result, the information carrier can be read out particularly safe and reliable. This can be done by touching or approaching a person as well as by coupling through an object.

Conductor tracks preferably consist of an electrically conductive layer and preferably produce an electrical connection between two or more subregions.

It was completely surprising that a touch structure and an antenna can be applied to an information carrier, wherein both electrically conductive layers are present in part on an electrically nonconductive material. For the purposes of the invention, the term "regionally" describes that the first and second layers do not completely cover the substrate, but are applied in a structured manner By virtue of the inventive combination of these two properties, electrical conductivity and structure, it is surprisingly possible to design a touch structure and to arrange an antenna on a substrate to provide a multiple information carrier.

Advantageously, the substrate in a preferred embodiment consists of a plastic, a paper, a cardboard, a wood material, a composite material, glass, ceramics, textiles, leather, a biodegradable plastic, at least one cellulose derivative, a starch derivative and / or a combination thereof , Of course, particularly advantageous are degradable substrates or a combination thereof. In particular, the substrate is an electrically nonconductive material which is preferably flexible and light in weight. Translucent or opaque substrates may be used. Preferred plastics include in particular PVC, PETG, PV, PETX, PE and synthetic papers. By the preferred substrate, an information carrier can be provided, which is inexpensive to produce by mass production method and has a low weight. In addition, the information carrier can be configured in a preferred embodiment as a flexible information carrier whose functionality is not affected by changes in shape (such as buckling or bending). It is preferred that the electrically conductive layer is a metal layer, a metal particle-containing layer, a layer containing electrically conductive particles, an electrically conductive polymer layer or a layer of at least one combination of these layers. Electrically conductive particles are in particular carbon black or graphite particles. In the context of the invention, polymers designate, in particular, a substance which is composed of a group of chemically uniformly structured but generally differing macromolecules with respect to the degree of polymerization, molecular weight and chain length (polymer molecules). The polymers are preferably electrically conductive. In such polymer-unitary substances, all macromolecules are preferably of identical construction and differ only in their chain length (degree of polymerization). Such polymers can be referred to as polymer homologs. Polymers may be selected from the group comprising inorganic polymers, organometallic polymers, wholly or partially aromatic polymers, homopolymers, copolymers, biopolymers, chemically modified polymers and / or synthetic polymers. Particularly preferred are polymers selected from paraphenylene, polyacetylene, polypyrrole, polythiophene, polyaniline (PANI) and PE-DOT. Thus, the information carrier is inexpensive to produce by means of a mass production process.

Since touch structure, comprising touch point, trace and / or coupling surface, and antenna preferably consist of the same or similar electrically conductive materials, an information carrier can preferably be produced by the application of a technological process. It is preferred that the first and second layers be a layer formed on the substrate by an additive, semi-additive and / or subtractive method. That is, both layers of the information carrier are preferably produced by a method. This represents a significant advantage over the prior art, since the information carrier is thus easily and economically produced in mass production process. The electrically conductive layer is realized according to a further preferred embodiment by applying a subtractive method, wherein layer regions are removed. In this case, known etching or laser ablation methods are used. In the latter, the material to be removed is vaporized by the action of the laser beams. Of course, other methods can be used. Suitable processes are preferably flat, high, deep and special printing processes. Particularly preferred are offset printing, flexo and inkjet processes.

The electrically conductive layer can be realized according to a further preferred embodiment by applying a subtractive method, wherein layer regions are removed. In this case, known etching or laser ablation methods are used. In the latter, the material to be removed is vaporized by the action of the laser beams. Of course, other, known in the art printing method can be used.

It is also preferable that the information carrier is manufactured by a transfer method. Preferably, the application of the touch structure and the antenna on the substrate can be effected by transfer methods known per se; this is preferably the transfer film process and particularly preferably a cold film transfer process. The person skilled in the art is aware of such methods and knows that it is possible by means of printing to pattern a substance (such as a touch structure or antenna), in particular to apply it on the substrate in some areas (for example US 3,719,804). The substrate is not completely covered by the touch structure and antenna, but the touch structure and antenna are present only on certain areas of the substrate. Of course, other methods for structured application of the electrically conductive layers can be used.

The touch structure can advantageously be read out with a capacitive area sensor, which can also be referred to as touch screen or touchscreen in the sense of the invention. It is preferred that the area sensor comprises at least one capacitive display. The area sensor can also be accommodated in an electrical device, wherein the device containing the area sensor is selected from the group comprising smartphones, mobile phones, displays, tablet PCs, tablet notebooks, touchpad devices, graphics tablets, televisions, PDAs, MP3 players , Trackpads and / or and capacitive input devices, without being limited thereto. For example, a capacitive area sensor can also be part of input devices as a touchscreen, touchpad or graphics tablet. Touch screens are also known as touch screen or touch screen. Such input devices are used, inter alia, in smartphones, PDAs, touch displays or notebooks. An area sensor does not necessarily have to be located in front of a display. For example, this can also be designed and used as a keyboard. In addition to a click function and a drag-and-drop operation is executable. Furthermore, a plurality of simultaneous touches in the form of a so-called "multi-touch" can be used to rotate, for example, displayed elements, in particular, or to scale them. The area sensor is preferably designed as a so-called projected capacitive touch technique (PCT) , Variants of the PCT technique include, for example, "Mutual Capacity" and "Seif Capacitance", which can be embodied as Mutual Capacitance Screen and Self Capacitance Screen.

In the prior art, such a touch screen comprises in particular an active circuit, the touch controller, which is connected to a structure of electrodes. These Electrodes are usually divided into transmitting and receiving electrodes. The touch controller preferably controls the electrodes such that a signal is transmitted between in each case one or more transmitting electrodes and one or more receiving electrodes. When idle, the signal remains constant. The purpose of a touchscreen described in the prior art is, in particular, the detection of fingers or special input devices and their position on the surface of the touchscreen. For this purpose, the introduction causes z. As a finger that the signal between the electrodes is changed. As a rule, the signal is reduced because the inserted finger receives part of the signal from the transmitting electrode and thus a lower signal arrives at the receiving electrode.

An advantageous feature of the touch structure is its conductivity. If, instead of a finger, a preferred information carrier with the touch structure is brought into contact with a surface sensor, the conductive regions preferably produce the same effect as a finger. However, the conductive structure is structured in regions, since on the one hand at certain points, in particular the touch points of the effect, which is comparable to the introduction of a finger, to be maximized in order to be the best possible recognizable for the touch controller. Thus, the touch structure can advantageously be evaluated for a data processing system connected to the area sensor.

A person skilled in the art knows that an input can be made on one touchscreen or one area sensor by means of one or more fingers (single or multi-touch). The technology of the surface sensors and the principles of the input, or by which properties of a finger an input takes place, are also known to the person skilled in the art. For example, in addition to the electrical properties of the finger (eg conductivity), density, pressure of the input or distance to the area sensor can also influence the inputs. The preferred information carrier achieves the same effect on a surface sensor as a finger by structuring the conductive region, namely an input on a position defined by the conductive regions of the information carrier on the surface sensor. The person skilled in the art would thus be able to carry out the touch structure of the information carrier without great experimental effort in such a way that their intrinsic properties are reproduced and an input to an area sensor can be achieved with the electrically conductive surfaces of the information carrier.

By way of example, but not limitation, of a preferred information carrier interacting with a so-called touch screen with an electrode arrangement in the form of a grid, for example, a suitable structuring of the touch point is a circle having a diameter of 1 to 20 mm, preferably 4 up to 15 mm and especially preferably 6 to 10 mm. Since a touch screen is suitable for determining the position of fingers, a touch point of an information carrier can likewise be determined by the touch screen in the same way. The touchscreen or area sensor advantageously can not distinguish whether the input was made by the touch structure of an information carrier or by a finger.

It may be preferable to apply a plurality of touch structures on a preferred information carrier. Advantageously, the shape, orientation, number, orientation, spacing and / or position of partial regions, preferably the touch points of the touch structure, can be used to store information. Information in the form of the touch structure, which may be designed as a subarea, is preferably stored on the information carrier. The information is readable when contacting or approaching the information carrier to the area sensor about this, wherein the capacity is in particular partially changed.

The information-forming touch structure, ie the subregions of a region, consist of an electrically conductive material. It is preferred that the first and second layers are patterned as a dot, dash, curve, surface and / or combinations thereof on the substrate. In a preferred embodiment, the first and second layers are arranged spatially separated, overlapping or congruent on the substrate. Advantageously, the first and second layers consist of corner points and / or fill surfaces defined by curves, for example rectangles, circles or similar figures. The local relationships of the subareas to one another (orientation, number, orientation, distance and / or position) and / or the shape of the subregions preferably represent the information. When positioning the information carrier on the area sensor, the touch structure, preferably the conductor tracks, becomes particularly Preferably, the coupling surface and most preferably the touch points interpreted as finger input, for example, so that from the sub-regions of the touch structure, in particular the touch points, the coded information can be determined, for example in the form of a binary coded number, without being limited thereto to be. In addition, an information carrier can be determined, in particular, in that the interaction between the information carrier and the area sensor, which is determined by the area sensor, represents the geometry given by the touch structure of the information carrier itself, a code in an encoding system. The positioning can also be done by a relative movement of the information carrier to the surface sensor. It is preferred that the area sensor in a movement relative to the information carrier progressively receives full or partial information from the information carrier. Depending on the position of the information carrier in relation to the area sensor, it is also possible to vary events are generated. Decisive for this, for example, the direction of movement or residence time of the information carrier relative to the surface sensor.

The antenna, which is applied as an electrically conductive layer on the electrically non-conductive substrate, is preferably an UHF antenna (UHF = Ultra High Frequency) or HF antenna (HF = High Frequency), in particular a dipole antenna, comprising two spaced-apart dipole ends. Advantageously, a maximum range can be achieved by the arrangement of the antenna on the substrate and the preferred embodiment of the antenna with a low material usage. Surprisingly, the structure of the antenna can be evaluated capacitively. The antenna according to the invention comprises a resonant structure in the form of the antenna, advantageously in the form of an RFID antenna. For the purposes of the invention, RFID designates in particular an identification with the aid of electromagnetic waves (Radio Frequency Identification). Such an RFI D system is known to consist essentially of a transponder, a transceiver for the data of the transponder and a data processing unit. The transponder preferably has a chip with an analog and a digital circuit structure and an antenna structure. The antenna structure may advantageously comprise a plurality of components, for example a resonant and / or impedance-adapting structure. These may be on a carrier or different carriers. It is preferred that a readable agent selected from the group consisting of inductive, acoustic, magnetic, electromagnetic and / or optical means is applied to the substrate. The means, which may also be referred to as basic technology, may preferably be embodied as readable codes which, for example, can be read out optically by specific wavelengths (eg from the ultraviolet or infrared range). In addition, the codes may be configured as 2-dimensional or 3-dimensional, so that they can be read by corresponding readers or area sensors. The codes which can be read out include preferably barcode, QR code, Aztec code, augmented reality tags, radio frequency resonance (RF) tag security tags, electromagnetic tag security tags (EM tag), aftermarket tags a harmonious process, AL-tag merchandise security tags (AM label), and RFI D tags. However, other readable inductive, acoustic, magnetic, electromagnetic and / or optical codes or means known to the person skilled in the art can also be present on the substrate. This increases the possibilities for reading the information carrier or the information carrier of the product. At the same time, a selective distribution of information on different information carriers enabling technologies. This can be advantageously used for product security, product tracking and / or sales increase.

In this way, a multiple information carrier can be provided in a simple manner, wherein the different range of the further readable means and the associated basic technology are a further positive criterion of the multiple information carrier. It is thus possible to completely or selectively capture the respective information carrier from 0 to 20m, with information carrier base technologies that overlap partially with regard to coverage. This increases the redundancy with regard to data retention in the event of a defect and / or loss of individual information carriers. Furthermore, it is preferable for the information carrier to have at least one cover layer that completely or partially covers the substrate and / or the electrically conductive layers. The cover layer is preferably an electrically non-conductive layer, preferably a paper layer, a film layer, a color layer, a lacquer layer and / or combinations thereof. This layer can perform several functions, including protection of the information carrier against external influences or defacing. For the purposes of the invention, the layer may be referred to in particular as a cover layer and may also be used as a substrate.

The antenna, in particular the information carrier, is preferably used as RFI D transponder, wherein the antenna is preferably a resonant adaptive structure and advantageously present with an impedance matching coil and at least one microchip electrically connected thereto in spatial approximation of 0-3 cm , The information carrier thus comprises a touch structure and an antenna. Preferably, a transponder is coupled to the antenna. The components of the transponder in the form of the coil and the microchip can also be applied to the substrate with the antenna in a further preferred embodiment. Advantageously, the coil can also be applied using the printing method which was used to produce the information carrier.

It is preferred that the coil and / or the microchip are arranged on a separate intermediate carrier and the intermediate carrier is preferably designed to be self-adhesive. In the self-adhesive version, the intermediate carrier is particularly easy to fix on the substrate.

In a further preferred embodiment, the antenna is arranged on or on a first object and the coil with at least one microchip electrically connected thereto on or on a second object, wherein the objects in spatial Approach of 0-3cm brought present. Thus, only by a conscious or unconscious approximation of the two components, an effective transponder. The antenna may preferably be part of a package while the microchip coil is mounted on an article for which the package is intended. By bringing together the object and the packaging, a complete RFID transponder is created.

It is preferred that there is at least one layer readable by a capacitive reader on the substrate. With the additionally applied layer advantageously a multiply readable information carrier can be realized. The applied layer can be referred to in the sense of the invention, in particular as an information layer. This layer is also preferably a structured layer. Advantageously, this is applied in a same step with the touch structure and the antenna, so that a very economically realized multiple information carrier is available. Advantageously, a capacitive reading device is used for decoding, detection and / or for reading the applied information layer. In this case, the active surfaces of the reading device are in particular designed so that the information of the information carrier can be read without any doubt. The reader is familiar with readers for the capacitive readout of an information carrier or data carrier (eg US Pat. Possible readers include, for example, capacitive readers. The application of an inductive layer, which can be read with an inductive reader, may also be preferred. Combined readout (capacitive / inductive) of such information carriers may also be preferred.

Furthermore, it is preferred that at least one optically readable structure, preferably a code, is applied to the substrate of the information carrier. Thus, an optically readable structure in the form of a code may be another preferred component of the information carrier, so that a further multiply readable information carrier can be realized. A known optically readable data medium is, for example, a barcode, SNAP code, QR code or AR system (Augmented Reality). This increases the possibility of reading a preferred product. This allows a continuous and redundant access to information, even if one of the information carriers can not be read out due to environmental influences such as dirt (bar code problematic), metallic substrates (RFID problematic) etc. Furthermore, a selective distribution of information to different basic technologies is made possible. This means that antennas and / or information carriers can be integrated into already existing or new products without any loss of time or special machines. brought. These are, for example, packaging, which can be used either for product security, product tracking and / or sales increase.

In addition, it is possible to read the information carrier over greater distances by means of the antenna transponder arrangement. Ranges of up to 20m or more are possible. While the readable with a capacitive reader layer can be read only in the near field (in particular a few millimeters). The same applies to inductive or optical codes, which reach a few cm range. A barcode can be read out over several decimeters. These combinations of different reading methods and ranges allow a very complex use and application of the information carrier without additional costs. The information carrier can advantageously be detected by means of various physical reading methods.

In a further preferred embodiment, the information carrier is connected to at least one further electrical component, comprising a galvanic element, a capacitor arrangement and / or a chip. The galvanic element advantageously leads to an active or at least semi-active information carrier. With the information carrier can thus also take an active data management, so that the potential applications are significantly increased.

It is further preferred that the information carrier is used as a multi-frequency RFID transponder, wherein at least one further RFID transponder of a further frequency range is arranged on or on the substrate. In this way, multiple RFID systems can be implemented as information carriers in which one RFID transponder can be read out over a greater distance, while the other RFI D transponder has a significantly shorter range due to the frequency and functional principle. As a result, both UHF and HF frequency bands can be utilized on an information carrier, which represents a further advantage.

The information carrier can preferably at the same time be a component of a packaging and / or an article and / or arranged thereon. Advantageously, the information carrier can be connected to an object or the object itself can serve as a substrate. The information carrier can be easily applied to various objects, wherein the surfaces of the objects need not be flat. The objects, in particular the surfaces of the objects, can serve as a substrate onto which the electrically conductive layer is printed. This results in the most diverse possible applications of the information carrier. It is preferred that the information carrier is used for the fact that the information carrier is at least a part of an illustration, a decoration layer and / or an optical finish. Advantageously, this can be realized quickly and easily with numbers, letters or characters. An example is a word with T where either the crossbar or the longitudinal beam can simultaneously be the antenna and portions of the longitudinal or transverse bar can be the touch structure. Furthermore, such imaging advantageously be used as a quality and authenticity feature, which is justified by the functionality of the information carrier.

The invention further relates to a group of information carriers comprising a plurality of information carriers wherein at least one color layer, adhesive layer, paper layer and / or film is applied at least as a background, coverage, number, letter, character, graphical representation and / or pictorial representation or a combination thereof , in which

a plurality of information carriers have an IT-like first and second layer and at least one identically designed ink layer, so that a self-contained group of information technology and optically identical information carriers is realized,

a plurality of information carriers have an information technology identical first and second layer and at least one differently designed color layer, so that a group of information technology same, but optically different, information carriers is realized,

a plurality of information carriers have an informationally unequal first and second layer and at least one identically designed color layer, so that a group of information technology unique, but optically identical, information carriers is realized,

- Have a plurality of information carriers informationally unequal first and second layer and at least one uneven color layer, so that optically and technically, unique information carrier are realized. The group of information carriers can be read out by means of a device having an area sensor. Advantageously, the group of information carriers can be combined with one another, whereby a plurality of information carriers can also be positioned and read out one above the other or next to one another on a surface sensor. In the following, the invention will be explained with reference to figures, but without being limited to these. Show it:

An assembly consists in a first embodiment substantially of a structured layer of an adhesive and a transfer layer disposed thereon as an antenna 2 on an electrically non-conductive substrate 1. The antenna is designed as a UHF dipole antenna and has two spaced-apart dipole ends. In this case, 2 different geometries are realized as an antenna 2 by way of example.

To produce an assembly, in a second embodiment, a transfer film method in the form of a cold foil method is used. It is particularly preferred to apply a structured adhesive to the electrically non-conductive substrate 1. The structuring and application of adhesives is technically very easily possible, in contrast to the at least partial removal of structures from a full-surface material. The latter is usually done by wet-chemical processes such as etching and is therefore very limited by the choice of substrate and the medium to be applied and therefore disadvantageous. The structuring of the adhesive further has the advantages of making very flexible layout changes or changes to the data structure. In a particularly preferred variant of offset printing, this is the replacement of an offset plate or a blanket.

In a further embodiment, the adhesive is first applied to the transfer film and then this at least partially adhesive transfer film is brought into contact with the substrate 1. It is particularly advantageous if the UHF dipole antenna and / or the capacitive information carrier 8 is part of a printed product, for example a packaging 4. The packaging 4 can be used for example for food, jewelry, cosmetics or in the medical field for the transport of important drugs or organs. Advantageously, use of the invention in all areas is possible and advantageous in which information is to be read out by means of RFID technology and / or capacitive reading technology.

Fig. 1 shows two different geometries of antennas 2 in a schematic representation. On the electrically non-conductive substrate 1, at least one structured layer of an adhesive and at least one electrically conductive transfer layer are arranged on this layer as the antenna 2. FIGS. 1 a and 1 b show, by way of example, different geometries of antennas 2. In FIG. 1 b, the antenna 2 is embodied as a UHF slot antenna 12. The transfer layer is advantageously a component of a transfer film. Another component of the transfer film is a carrier of the transfer layer. The compound of the two constituents is designed such that the adhesion capacity of the structured adhesive layer is higher than the cohesiveness of the transfer layer and the adhesiveness of the substrate 1. The transfer layer preferably consists of particles or contains particles which consist of metal, at least one metal alloy, graphite, a dielectric substance individually or in at least one combination. The antennas 2 are preferably applied to objects or packaging 4, which at the same time adds to the increase in sales the optical processing around the antenna 2, for example for product safety. This produces a cost-neutral and realized without additional effort antenna 2. In a particularly preferred embodiment, even the optical processing can be performed simultaneously as an antenna 2. The electrically nonconductive substrate 1 is preferably a carrier medium, which may be made of paper, cardboard, a wood material, rubber, glass, a composite material, a plastic, a biodegradable plastic, at least one cellulose derivative, at least one starch derivative or at least one combination thereof consists. Of course, particularly advantageous are degradable substrates 1. More preferably, the paper is made of pulp or wood pulp made of wood pulp. The paper may be in the form of cardboard or cardboard, for example. For these applications, paperboard is a material made of pulp or waste paper by gluing or pressing together. The paperboard may be a paper body glued together from one or three or more plies, in which the topsheets and middle plies have the same or different composition, for example by making the topsheets from wood-free fabrics and the middle plies from wood-containing ones Be provided. Another preferred substrate 1 is plastic. It may preferably be polyethylene, polypropylene, polyvinyl chloride, polystyrene, polycarbonate, polyurethane, PVDF, polyethylene terephthalate or co-polymers of the aforementioned. The use of biodegradable films of corn starch and cellulose derivatives may also be preferred. The functional layers for the antenna 2, the information layer in the form of a capacitive information carrier 8 and / or the optical layer in the form of an optical code 9 may preferably be metals or metal-containing substances, such as cold foils with an aluminum or other transfer layers or else the aforementioned dielectric materials or graphite and carbon black. A very good electrical conductivity is not completely necessary for this application completely surprising. Positive results could be achieved even with sheet resistances of more than 100Q / D. The electrical conductivity can be referred to in the context of the invention, in particular as a conductance. Preferred metals or metal-containing substances include aluminum, lead, iron, gold, copper, magnesium, tungsten, zinc or tin. Of course, it is also possible that the metals or metal-containing substances include elements such as chromium, molybdenum or others. Dielectric materials is any electrically weak or non-conductive, non-metallic substance whose charge carriers are generally free to move. This may be, for example, electrically conductive plastics such as PEDOT and PANI.
