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?
