NFC

[pareshvaland]

Hi,

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.

Hi Paresh Valand,

The antenna design in SW3639 is used for NTAG plus Explorer Kit, so it meets NFC spec, but the maximum distance depends on the antenna design on the reader side. so the parameters you may find in NTAG Antenna Design Guide .

Hope that helps,

Have a great day,
Kan
