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:
- Print until paused.
- 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).
- Continue printing.
- Solder an SMA edge connector to the end of the wire.
- If necessary, glue the connector inside the model for stability.
