|Issue Date:||2018||Publisher:||Institute of Electrical and Electronics Engineers (IEEE)||Project:||SURF (TEC2014-60527-C2-1-R)||Conference:||61st IEEE International Midwest Symposium on Circuits and Systems, MWSCAS 2018||Abstract:||In this paper we obtain the effective geometrical parameters of a ferrite-core based antenna to model its equivalent electrical circuit for computing the self-inductance, power losses, including the hysteresis effects. The ferrite coil is the receiver antenna of a low frequency RFID tag (134.2 kHz). Non-linear effects are modeled by adjusting the hysteresis angle and effective radius of the ferrite core-based coil. In addition, we modeled the coupled equivalent circuit of the RFID system and computed the mutual inductance at different Z-axis values. Numerical analysis using FEM in 2D is used. These models have been validated with experimental measurements of S11 scattering parameter and induced current, respectively.||URI:||http://hdl.handle.net/10553/69824||ISBN:||978-1-5386-7392-8||DOI:||10.1109/MWSCAS.2018.8623854||Source:||61st International Midwest Symposium on Circuits and Systems (MWSCAS), Windsor, ON, Canada, 2018, pp. 1020-1023|
