Description

RFID-Transponder mit einem flexiblen Antennenkörper  RFID transponder with a flexible antenna body
Beschreibung description
Die Erfindung betrifft einen RFID-Transponder mit einem flexiblen Antennenkörper. The invention relates to an RFID transponder with a flexible antenna body.
RFID-Transponder werden für die verschiedensten Anwendungen eingesetzt, beispielsweise zum elektronischen Identifizieren von Gegenständen oder Zuchtvieh, wie beispielsweise Rindern, Schweinen und Schafen mittels flexibler Ohrmarken. Dazu werden häufig flache Antennen benötigt, die sich für besondere Anwendungsfälle auch flexiblen Oberflächen angleichen lassen und gleichzeitig gegenüber rauen Umgebungsbedingungen geschützt sind. RFID transponders are used for a variety of applications, for example, for the electronic identification of objects or breeding cattle, such as cattle, pigs and sheep by means of flexible ear tags. This often flat antennas are needed, which can be adapted for special applications, even flexible surfaces and are protected against harsh environmental conditions.
Stand der Technik State of the art
Die Druckschrift WO 2006/091765 A2 schlägt ein Identifikationssystem für Tiere mittels Ohrmarken vor, bei dem ein RFI D-System zum Einsatz kommt, das den selben Identifikationscode auf zwei verschiednen Frequenzen über zwei Antennen überträgt. Der HF-RFID-Schaltkreis ist dabei nicht sichtbar und mit einer Plastikschicht überspritzt, um die Schaltkreiskomponenten vor Abnutzung und Umwelteinflüssen zu schützen. Die Druckschrift US7,649,463 B2 offenbart eine Antennenstruktur für einen RFID auf der Basis einer mehrschichtigen Folie. Dabei ist eine nicht geschlossene Loop-Antenne als Streifen ausgeführt und leitend mit einer Gitterstruktur verbunden. Weiterhin ist es offenbart, die Anordnung durch eine Polymerschicht zu versiegeln. The publication WO 2006/091765 A2 proposes an identification system for animals by means of ear tags, in which an RFI D system is used, which transmits the same identification code on two different frequencies via two antennas. The RF RFID circuit is not visible and over-molded with a plastic layer to protect the circuit components from wear and environmental impact. The document US Pat. No. 7,649,463 B2 discloses an antenna structure for a RFID based on a multilayer film. In this case, a non-closed loop antenna is designed as a strip and conductively connected to a grid structure. Furthermore, it is disclosed to seal the assembly by a polymer layer.
Solche Folien werden auch als sogenannte„SmartLabels" bezichnet und werden im Stand der Technik oft durch Umspritzen oder durch sogenanntes „umhäusen" geschützt. Such films are also referred to as so-called "SmartLabels" and are often protected in the art by overmolding or by so-called "sheathing".
Weiterhin sind RFID-Transponder auf der Basis flexibler Leiterplatten („flex- PCB") bekannt, die sich durch die Multilayer-Technologie mechanisch robust verpacken lassen. Ein Nachteil im Stand der Technik besteht somit darin, dass mechanisch flexible und gleichzeitig umweltresistente RFID-Transponder aufwendig herzustellen sind. Furthermore, RFID transponders on the basis of flexible printed circuit boards ("flex-PCB") are known which can be mechanically robustly packaged by the multilayer technology A disadvantage in the state of the art is therefore that mechanically flexible and at the same time environmentally resistant RFID transponders are expensive to produce.
Aufgabenstellung task
Die Aufgabe der vorliegenden Erfindung besteht somit darin, einen mechanisch flexiblen und umweltresistenten RFID-Transponder anzugeben, der mit möglichst geringem Aufwand herstellbar ist. Diese Aufgabe wird dadurch gelöst, dass der Antennenkörper zumindest bereichsweise eine mechanische Gitterstruktur aufweist, und dass der Antennenkörper aus einem leitfähigen Material besteht und/oder mit einem leitfähigen Material beschichtet ist. Dabei bedeutet das Kennzeichen„dass der Antennenkörper zumindest bereichsweise eine Gitterstruktur aufweist", dass der Antennenkörper mehrere, bevorzugt mindestens vier, insbesondere mindestens neun, besonders bevorzugt zweiundfünfzig kleine Fenster aufweist, wobei diese kleinen Fenster einander in ihrer Form gleichen und in einem flächigen Muster, bevorzugt in äquidistanten Intervallen, angeordnet sind. Bevorzugt handelt es sich bei der Form der kleinen Fenster jeweils um ein Rechteck, insbesondere um ein Quadrat. The object of the present invention is therefore to provide a mechanically flexible and environmentally resistant RFID transponder, which can be produced with the least possible effort. This object is achieved in that the antenna body at least partially has a mechanical lattice structure, and that the antenna body consists of a conductive material and / or is coated with a conductive material. The indicator "that the antenna body at least partially has a lattice structure" means that the antenna body has a plurality, preferably at least four, in particular at least nine, more preferably fifty-two small windows, these small windows are similar in shape and arranged in a planar pattern, preferably at equidistant intervals. The shape of the small windows is preferably a rectangle, in particular a square.

Fig.1 und Fig.2 stellen einen RFI D-Transponder dar. Dieser RFID- Transponder besitzt einen Antennenkörper 1. Der Antennenkörper 1 umfasst einen großflächigen Bereich 2 und ein großes quadratisches Fenster 5. Der großflächige Bereich 2 weist eine Gitterstruktur auf, d.h. er weist eine Viel- zahl symmetrisch zueinander angeordneter kleiner quadratischer Fenster 3 auf. Diese kleinen quadratischen Fenster 3 sind in äquidistanten Intervallen angeordnet und bilden ein flächiges Muster. Das große quadratisches Fenster 5 ist angrenzend an einen Bereich 6 einer ersten Seite 4 des Antennenkörpers 1 angeordnet. 1 and 2 illustrate an RFI D transponder. This RFID transponder has an antenna body 1. The antenna body 1 comprises a large area 2 and a large square window 5. The large area 2 has a grid structure, i. it has a multiplicity of small square windows 3 arranged symmetrically with respect to one another. These small square windows 3 are arranged at equidistant intervals and form a planar pattern. The large square window 5 is disposed adjacent to a portion 6 of a first side 4 of the antenna body 1.
Fig.3 stellt einen vergrößerten Ausschnitt aus Fig.1 dar. An dem Bereich 6 (dargestellt in Fig.1 und Fig.2) sind an den Antennenkörper zwei zueinander spielgelsymetrische, einander entgegengesetzt meanderförmig gebogene Stege 7,7' angeformt, die einander weder schneiden noch berühren, wodurch die erste Seite 4 eine sich zu ihrem Inneren hin verbreiternde Einbuchtung 8 besitzt. Durch diese Bauform entsteht eine offene Loopantenne 2, indem die Stege 7,7' mit ihren jeweiligen freistehenden Enden elektrisch leitend an einen RFID-Chip 9 angeschlossen, d.h. über den RFID-Chip 9 lei- tend miteinander verbunden sind. Dieser elektrische Anschluss wird durch Verlöten, insbesondere durch Reflow-Verlöten hergestellt. FIG. 3 shows an enlarged detail of FIG. 1.

This design results in an open loop antenna 2 in that the webs 7, 7 ', with their respective freestanding ends, are connected in an electrically conductive manner to an RFID chip 9, ie via the RFID chip 9. tend to be interconnected. This electrical connection is made by soldering, in particular by reflow soldering.
Fig. 4 stellt den RFID-Chip 9 in einem vergrößerten Ausschnitt aus Fig.3 dar. Aus dieser Perspektive wird ersichtlich, dass der RFID-Chip 9 auf den offenen Enden der beiden Stege 7,7' angeordnet ist. FIG. 4 shows the RFID chip 9 in an enlarged detail from FIG. 3. From this perspective, it can be seen that the RFID chip 9 is arranged on the open ends of the two webs 7, 7 ' .
