I am trying to make one page that contain all the useful information about NFC Antenna Design. I will keep update and add the information to this page when I found something useful.
Training
First of all, there are 6 webinars about NFC Antenna Design. It is a good training before to start your antenna design for NFC.
I tried NFC ntag plus and I downloaded antenna layout for Eagle from here: https://community.nxp.com/thread/446368. Please, have you got something like that for Eagle for PN7150/PN7120?
