I would like to connect a 1.4uH antenna to ST25DV-I2C.
The datasheet says that there is a 28.5pF capacitor inside the IC for RF interface tuning.
However, when using a 1.4uH antenna, the resonant frequency shifts from 13.56MHz.
How should I adjust the resonant frequency?
Also, are there any application notes that describe how to adjust the resonant frequency?
