Hi Antonio,

please find below the Layer stack + material used for the NFC05A1.

Since the antenna is mainly on one layer, the stack-up will not influence the impedance so much. 

Also differences in the used dielectric characteristic of the material can be compensated by the AAT feature of the ST25R3911B.
