Abstract

The paper presents the results of investigations on planar inductors realized on flexible substrates for RFID antennas. The electrical parameters as: inductance, quality factor, self resonance frequency will be on the focus field. These parameters depend on inductor layout and on properties of materials used for realization. The inductor windings can be screen printed or jet printed with silver ink or can be obtained by etching a layer of deposited copper. The electrical behavior of the inductance will be pre-determined by Finite Element Analysis (FEA) in the electromagnetic domain. It was possible to extract a SPICE equivalent model for the inductor and hence to determine the frequency behavior.
