Regarding the reader HF ST25R3911B nucleo board X-NUCLEO-NFC05A1: is possible to have also the stack-up and the infos on built materials in order to have the right impedances ?

Thanks a lot

    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.
