Method for Providing Inductively Coupled Radio Frequency Identification (RFID) Transponder, and RFID Transponder
First Claim
1. A radio frequency identification (RFID) transponder for an RFID arrangement having inductive coupling, comprising:
- a transmitting and receiving coil; and
a ferrite component for guiding a magnetic flux, the ferrite component for guiding the magnetic flux interacting with the transmitting and receiving coil and comprising a composite material comprised of a plastic and ferrite powder, and the plastic being furnished in a laser-patternable manner;
wherein the transmitting and receiving coil is formed by at least one conductor track metalized and precontoured by laser processing in or on a surface of the component.

Abstract
A radio frequency identification (RFID) transponder for use in an RFID arrangement with inductive coupling, where interaction of a transmitting and receiving coil with a ferrite component is provided for guiding the magnetic flux. Here, the ferrite component for guiding the magnetic flux includes a composite material comprising a plastic and ferrite powder, where the plastic is furnished in a laser-patternable manner, such that the transmitting and receiving coil is formed by at least one conductor track and then precontoured by laser processing metalized in or on a surface of the component. Such an RFID transponder is robust, easy and simple to produce.
