| A new radio frequency identification devices (RFIDs)system operating at very lowfrequencies (in 1Hz to 100 kHz range)has been developed and tested. This frequency range has the advantage of the avoiding screening problems that commercial technologies undergo. The new system can operate through thick magnetic shielding layers and in metallic non-cleaned surroundings. This capability is based on measuring the magnetization changes of a magnetic core integrated in the tag. The tag associated circuit does not need to be resonant that is necessary in a system that works at low frequencies. A simple theoretical model has been developed and experimentally tested; it allows the design of new systemswith different geometries. | |
