I am designing a board that will have NFC capabilities and am wondering if it is ok to just have the antenna go around the outer perimeter of the board and have the components in the center?
Hi,
Having the componentes outside the antenna space is the best option, but if you have size constraints you can have components inside the antenna area. You need to follow these considerations:
I recommend to check the specific NFC Reader antenna design guide. As example, you can see the PN5180 NFC Reader Antenna Design guide document https://www.nxp.com/docs/en/application-note/AN11740.pdf
Hope the information hepls,

That's very useful information, thanks Adrian. Can I extend Nate's question and ask what clearance should be respected around the PCB antenna? I can't seem to find that information in the documentation you linked. I'm looking at a Class 1 type antenna.
Thanks,
