Abstract

RFID transponder with a flexible antenna body, characterized in that the antenna body (1) at least partially has a lattice structure and that the antenna body (1) consists of a conductive material and / or coated with a conductive material.

Description

  • The invention relates to an RFID transponder with a flexible antenna body.
  • 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.
  • State of the art
  • The publication WO 2006/091765 A2 proposes an identification system for animals using ear tags, in which an RFID 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 publication 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.
  • Such films are also referred to as so-called "SmartLabels" and are often protected in the art by overmolding or by so-called "sheathing".
  • Furthermore, RFID transponders on the basis of flexible printed circuit boards ("flex-PCB") are known, which can be packed mechanically robust by the multilayer technology.
  • A disadvantage in the prior art is therefore that mechanically flexible and at the same time environment-resistant RFID transponders are expensive to produce.
  • task
  • 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.
  • In this case, the indicator "that the antenna body at least partially has a lattice structure" means that the antenna body has several, preferably at least four, in particular at least nine, more preferably fifty-two small windows, these small windows are similar in shape and in a two-dimensional pattern, preferably at equidistant intervals, are arranged. The shape of the small windows is preferably a rectangle, in particular a square.
  • Advantageous embodiments of the invention are specified in the dependent dependent claims 2-10.
  • The invention relates to an RFID transponder, which is produced, for example, from a stamped sheet as the base material or produced by injection molding from a plastic as a base material and coated with a conductive material.
  • This has the advantage that such transponders can be produced inexpensively with devices and methods already available from many manufacturers.
  • It is particularly advantageous that the antenna body by its lattice structure on the one hand has a relatively high mechanical flexibility in spite of its basically relatively rigid base material and on the other hand, because of the solid base material is resistant to destructive environmental influences.
  • In a preferred embodiment, a loop antenna is electrically conductively connected to the metallized grid structure. Preferably, the loop antenna and the antenna body are made in one piece. This is preferably a loop antenna in an open, d. H. non-enclosed design, which is connected on both sides to an RFID chip. In a preferred embodiment, the loop antenna is arranged within the antenna body in a large window. Preferably, the loop antenna is a pair of arcuate webs that are mirror-symmetrical to each other and preferably each have a meandering course, ie. H. are each formed substantially S-shaped. Preferably, the RFID chip is soldered to the ends of the two webs to the loop antenna. In particular, the soldering can be done by a reflow soldering process.
  • In a preferred embodiment, the RFID chip is environmentally safe packed and / or housed, for example by encapsulation.
  • In a further preferred embodiment, the loop antenna is arranged in a recess of the antenna body. Preferably, the loop antenna is part of the one-piece antenna body. Thus, the antenna body is formed integrally with the loop antenna and made of the same base material in the same manufacturing process.
  • In a preferred embodiment, the base material is a stamped sheet, which is stamped accordingly. in particular, the small windows are punched out of the stamped sheet. The large window in which the loop antenna is arranged, as well as the loop antenna itself, are also punched out of the sheet. In this case, the loop antenna can preferably be formed from two webs bent in a meandering manner, their open ends being conductively connected to one another via an RFID chip.
  • It is particularly advantageous that the inventive design of the RFID transponder relatively inexpensive and inexpensive manufacturing process allows, for example, roll to roll manufacturing, in particular roll to roll punching, and roll to roll metallization, in particular by punching. In particular, the lattice structure allows a very good clawing of the housing plastics, for example during encapsulation.
  • embodiment
  • An embodiment of the invention is illustrated in the drawing and will be explained in more detail below. Show it:
  • 1 an RFID transponder with a flexible antenna body in a plan view.
  • 2 an RFID transponder with a flexible antenna body in an oblique plan view.
  • 3 a loop antenna of the antenna body in a plan view.
  • 4 the loop antenna in an oblique plan view.
  • 1 and 2 represent an RFID transponder. This RFID transponder has an antenna body 1 , The antenna body 1 covers a large area 2 and a big square window 5 , The large area 2 has a lattice structure, that is, it has a plurality of symmetrically arranged small square windows 3 on. These little square windows 3 are arranged at equidistant intervals and form a planar pattern. The big square window 5 is adjacent to an area 6 a first page 4 of the antenna body 1 arranged.
  • 3 represents an enlarged section 1 at the area 6 (shown in 1 and 2 ) are on the antenna body two mutually play gel symmetrical, mutually opposite meandering curved webs 7 . 7 ' molded, which neither intersect nor touch each other, eliminating the first page 4 an indentation broadening towards its interior 8th has. This design creates an open loop antenna 2 by the webs 7 . 7 with their respective freestanding ends electrically conductive to an RFID chip 9 connected, ie via the RFID chip 9 are conductively connected to each other. This electrical connection is made by soldering, in particular by reflow soldering.
  • 4 puts the RFID chip 9 in an enlarged section 3 From this perspective, it can be seen that the RFID chip 9 on the open ends of the two webs 7 . 7 ' is arranged.
