If you're considering designing your own antenna, calculating existing antenna parameters, or matching your antenna to the NFC Reader or Tag IC, you'll find a variety of online tools that can be invaluable for these tasks.
NFC Antenna Design Hub
It's a comprehensive tool developed by NXP Semiconductors, integrating an antenna calculator with a matching network calculator tailored specifically for NXP NFC Readers and NFC Tags.
The tool is conveniently available online, eliminating the need for downloads or registrations. NXP has provided default values for each NFC Tag and Reader, serving as excellent starting points. Users can easily download the results in PDF format for their convenience.
