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: | https://accedacris.ulpgc.es/handle/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 |
