NHS3152 Antenna Design Tool or Ressources

[jr1]

Hi,

I have been testing the NHS3152TEMOADK kit and now I would like to make my own PCB

I couldn't find documentation or desuígn tool about antenna for NHS3152 , do you have some ressources, documentation about antenna design for NHS3152 ?

Hello, my name is Fabian, I've been assigned to support your case.

Thank you for your interest in our products

Please download the following file:  NHS3100 SDK - v12.6 (release_mra2_12_6_nhs3100) file from: https://www.nxp.com/products/rfid-nfc/nfc-hf/ntag-smartsensor/ntag-smartsensor-with-temperature-sens... in the software section /

please find follow the next path: …\release_mra2_12_6_nhs3100\docs\NHS3100 Therapy Adherence.zip

You will find the schematics and gerbers.

Unfortunately, this all the documentation we have regarding antenna design of the NHS3152.

Hi Fabian, 

   Recently we are using NHS3152 to design for some small tags, so I want also to ask the antenna of NHS 3152 doesn't need to do the impedance matching？ If need, is the impedance should be 50omi？ If doesn't need, should we just concern about the Resonant Frequency  of the antenna?

   Hoping for your kindly reply.

Hello sir,

The only infromation we have regaridng the antenna design for tags, is the following: https://www.nxp.com/docs/en/application-note/AN11276.zip

Please let me know if this information was useful.

Hello sir,
Unfortunately, the content of the downloaded directory is the only documentation we have. My apologies but, we don’t have any tests or antenna performance documentation.

Hello Fabian,

Thanks for the answer

If I copy the antenna from the gerber files (with the same dimension, width, number of turns...) I can directly connect it to the NHS3152 ?

[Fabian_R]

Hello sir,

This is correct nevertheless, please keep in mind that is possible that the antenna performance may slightly change due to the board design. I cannot assure that it will perform equally as the evaluation board since your full design won't be exactly the same. My recommendation is to perform some tests and, adjustments in the capacitor if needed.

Hello Fabian,

Thanks for the answer, I will order the PCB.

Do you have documentation / ressources for concerning the tests and adjustements I will have to perform to verify the antenna ?

Thanks and best regards
