1 Multilayer Ferrite Coil MLJ Series Ferrite coils support NFC circuits ideally The number of smartphones and other compact mobile devices that are “NFC-compliant” or “NFC-equipped” The inductance of the antenna is defined by its coil-geometry and the capacitance is determined by the dielectric properties of the substrate FR4. Tolerance variations in FR4 thickness and dielectric constants are well documented in [1], [2] and [3]. A study was performed in order to demonstrate the impact of manufacturing tolerances on the resonance drifts. Figure 2 shows published measurement data [4] for real and imaginary dielectric constant variations versus frequency.
