This is my first time in this forum.
I am a new developer and I am currently trying to build a custom NFC portable reader device.
I have already successfully used the MFRC522 arduino module. But now, I need a smaller solution, so I found out that I can use an IC reader (Standard performance MIFARE® and NTAG® frontend|NXP ). I guess that I need to connect this IC with an external antenna.
Are there any compatible antennas available?
I have no expertise in building and tuning one by myself, and a small external antenna is needed for my project. I am looking forward to any suggestions.
