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

What model printer, and what make ink?
Just curious.
