Question about NTAG I2C plus Flex Antenna Class6.

[gxu]

Hello,

We are doing a project with your NFC chip NT3H2111. In this project, NTAG I2C plus Flex Antenna Class6 was adopted.  We want to design a new PCB which includes this antenna Class 6, but we could only download a Gerber document about it . Could you please send us a PCB document about NTAG I2C plus Flex Antenna Class6?

Hello Kan,

I prefer 1 too, but I still haven't got layout for antenna for Eagle. I cannot import any file, which you recommended me.

Thank you.

Best Regards,

Vilem

Hi,

Actually the PCB document come along with the Gerber document, you may fetch it from http://www.nxp.com/documents/software/SW3646.zip. Anyway, I attached it here for your convenience and you should use EAGLE to open that file.

Hope that helps,
Have a great day,
Kan

Hi,

these files really helped me too. But now, I want try PN7120 or PN7150, but I cannot find something like that for Eagle software. Please, could you help me? Have you got any similar files for PN7120 or PN7150? 

Thank you very much!

Best Regards,

Vilem

Hello Kan,

thank you very much for the fast reply and for the links. I tried use it in eagle, but I cannot import the BRD files. Maybe, it is not for Eagle. I need mainly antenna for my design. 

And one additional question. Can I use external antenna - for example this: https://www.molex.com/molex/products/datasheet.jsp?part=active/1462360031_ANTENNAS.xml&channel=Produ...

Thank you.

Best regards,

Hello Vilem,

We have a NFC antenna dev kit available, NFC Antenna Development Kit | NXP , why not use this?

Have a great day,
Kan

Hello Kan,

Thank you, it looks good for development. But I need something low-cost for small production, too.

I have two solutions:

1. PN7150 + own antenna on own PCB

2. PN7150 + cheap external antenna + own PCB for PN7150 only

Thank you.

Best Regards,

Vilem
