Hi

The schematic looks correct. To avoid getting hard to find capacitor values for C125 and C126, it's a good idea to place a empty footprint in parallel with each of the caps. It makes NFC antenna tuning easier. 

 

best regards,

Your dual antenna arrangement won't work unless you lay it out correctly.

Ketil, Attached is a report where our antenna was tested. Can you review and comment?

[jimhan1960]

Can you be more specific as to the arrangement issues? Did you notice the placement of the LNA's behind the splitters, these would be more effective in front yes?

What LNA are you referring to?  There isn't one on your design.  I see two antennae slapped together with some caps. That won't work.
