Simulation and Measurements of Electric and Magnetic Fields of an RFID Loop Antenna Anti-Theft Gate SystemPublished online: Dec 22, 2010
The radiation of RFID anti-theft gate system based on two parallel coaxial square loop antennas has been analyzed. The system was simulated in FEKO and near electric and magnetic fields have been calculated. A physical model of the system was realized and near magnetic field was measured. Measurement results were found to be in excellent agreement with the simulation. The obtained simulation and measurement results have been compared to the exposure limits given as reference levels in the ICNIRP guidelines. No violation of limits has been shown, regarding both occupational and public exposure.
