PN7150 NFC antenna

[candid]

Hello.

   I read the PN7150 Antenna Design and Matching Guide (REV 1.6) and the PN7150 Hardware Design Guide (REV 1.2). But I did not understand, how can I make an antenna of the smallest size?
   I make an NFC tag reader (ring tag), and the antenna size should be as small as possible. I don’t need speed to read classic tags, only to work stably.

   Are there any examples, schemes that will help me to do this?

   Or maybe there are some antenna chips?

Best regards.

hello, i am having similar question, instead of using antenna tuning circuit, which almost includes around 20 Resistor, Capacitor , Inductors. so to reduce the components and PCB size i would like to add RF Balun at the replacement of tuning circuit, so could you please let me know if there is such a Balun is available or not?
