I was trying to fabricate a flexible NFC antenna for m24lr chip. Initially, I fabricated my design on a copper PCB. It worked perfectly fine with my NFC chip and facilitated NFC communication. I observed its S11 curve using a NanoVNA with a loop prob...

I am attempting to create an NFC antenna for the M24LR04E-R chip, following the circuit diagram of the x-nucleo-nfc02a1 board. My challenge is that the x-nucleo-nfc02a1 board uses a double-sided antenna, but I want to design a single-sided antenna th...
