AB  - RFID systems are sensitive to metallic environments in the proximity of the reader antenna. These influences produce shifting of the resonance frequency, causing performances degradation for the entire RFID system. Based on the behavior analysis of an HF RFID antenna circuit in the proximity of metallic environments, in this paper are proposed two tuning methods using a simplistic approach and some mathematical determinations. These solutions can be taken into account when it’s necessary to implement a HF RFID system that can offer good performances even if the metallic environments in the proximity of the antenna are constantly changing.<p>DOI: <a href="http://dx.doi.org/10.5755/j01.eee.18.9.2803">http://dx.doi.org/10.5755/j01.eee.18.9.2803</a></p>
