  • Abstract
    This paper presents a double resonance UHF RFID antenna suitable for most capacitive chips. The antenna incorporates two inductive loops that facilitate broadband matching. The paper studies how different dimensions in the antenna affect the input impedance. It is shown that the input impedance can be tuned with three structural parameters. The wide impedance bandwidth of the antenna improves the antenna performance when the environment varies making it more robust.
