NFC Aerial?

[M1che1l3]

Hi there,

I am about to start my first attempt at putting anything like this together. I plan to build this with the arduino primo core to reduce size a little. I was originally planning to keep the two poker-chip sized discs separate and connect them with a wire (rather than stacking them) so the part with the nfc reader could be worn on top of the libre sensor and the other part be worn next to it to reduce the added height.

I am not experienced with this sort of thing, but I was wondering if anyone has tried adding a nfc antenna* to increase the space it can be worn away from the libre sensor? I was thinking if it had a range of up to 0.5m-1m the arduino primo core could possibly be worn like a badge or button on clothing or even a necklace or earring in a 3d printed case if it had a little more reach?

*edit: would something like this work? (https://www.alibaba.com/product-detail/13-56mhz-NFC-chip-antenna-for_60328506427.html) - perhaps even sticking one inside the case and one onto the libre sensor... at US$0.25 a go it's affordable.

Thanks,

Michelle

*edit, realised this is called an antenna, not aerial
