I am using NFC I2C  ( NT3H2111) plus chip for my design. 

I have seen the reference design of antenna which showing only single side etch layer is used.

Can I use both top and bottom side for antenna layout ?

I have referred the reference antenna design of SW3639.

If I use same antenna design in sw3639 than what is the maximum distance I can connect the phone to tag ?

Let me know the antenna design parameter for sw3639.
