NFC Antenna for SDR sniffing

For analyzing NFC communication in an NFC Laboratory, an SDR and a suitable antenna are essential. While a simple close-distance antenna can be made with a few turns of magnetic wire, this 3D model offers a more robust and professional alternative to a makeshift wire taped onto a piece of paper.

Instructions:

1. Print until paused.
2. Wind a few turns of wire and leave a few centimeters of wire extending outside the model (ideally, tape it down outside the model to keep it out of the way of the extruder).
3. Continue printing.
4. Solder an SMA edge connector to the end of the wire.
5. If necessary, glue the connector inside the model for stability.
