I am examining the antenna attached to X-NUCLEO-NFC08A1 and its schematics, and I noticed that there is a 3rd pad at the edge of the antenna board with a connection to GND. I also see the same GND connection through a 0Ω resistor in the provided schematic in DB4702.
I've never seen this before in other NFC antenna designs. It seems to short the entire antenna to ground according to the multimeter. What is the purpose of this connection, and will my antenna still work without it? Thank you in advance.
Solved! Go to Solution.
