Inductive coupled RFID transponder

摘要

The transponder has a transmission- and reception coil (SP) in cooperation with a laser-activated ferrite compound (LAFC) for guiding magnetic flux, where the coil and the ferrite compound form an integrated component. The compound is formed from composite material made of plastic i.e. liquid crystal polymer, and ferrite powder, where the plastic is laser-structurable. The coil is formed by a conductor path (LB) pre-contoured and metallized by a laser machining process in or on a surface of the compound. Electronic components of an operating electronic circuit are attached to the compound. An independent claim is also included for a method for manufacturing an inductive coupled radio frequency identification (RFID) transponder.
