Hi,
I have an inkjet printer at hand that is able to print conductive silver ink. This is nice since you can easily try out different designs. Now I would like to print a 13.56MHz antenna for NFC. Does anyone know where I could download a layout file (EPS, PDF, CAD, ...) of some standard NFC antenna? I tried to find, but could not find any. By the way, the sheet resistance of the printed silver is 0.6 Ohm/sq. and I would like to print on Mylar foil (dielectric constant around
3). Any suggestion is welcome. I know that a lot of effort will be required to optimize the structure, but I am really looking for a starting point, something that works a little bit, as to act as a proof of concept.
Thanks, David
