ready-to-use antennas for PN532

Hello everyone.

 

For a project I need a NFC chip as a communication interface to a mobile phone. It would be ok to communicate directly with the phone or to write to a MIFARE Classic tag which is then read by the phone.

 

Due to software design reasons, it has to be the PN532 chip.

For functional prototyping I used an Arduino Uno and a PN532 breakout board which worked very well. 

I would immediately use such boards as they are, but unfortunately the antenna is too big for my use case. The antenna's dimensions must not exceed 20mm x 60mm.

The problem is that I have no background in the RFID/NFC technology, especially in designing custom antennas.

 

Therefore, I would really appreciate any tips,

(1) if there are ready-to-use antennas that are compatible with the PN532 chip and just have to be connected/soldered to it or

(2) if there are any breakout-boards available in my required dimensions (I did not find any) or

(3) if there is a way to reuse existing components (e.g. parts of such breakout boards, and just replace antenna) to build a new module to overcome my lack of knowledge.

 

 

Thank you very much!

Lukas
