“…For an optimised UHF RFID tag and reader system read ranges of >10 metres are common, but for very small tags incorporating small low efficiency antennas this distance is much reduced, with read ranges of 0.5 -2 m being typical [1] - [5]. A technique has been previously applied where everyday metallic tubular objects have been given UHF RFID functionality [6]. This paper demonstrates an efficient technique where the actual metallic instrument itself is modified and forms the antenna, with associated electronics such as the RFID device and additional matching components if required being embedded within the instruments body.…”

This paper details a technique where a nonresonant metallic surgical instrument -in this case a scalpel handle -can be modified to effectively incorporate UHF RFID functionality, where the instrument itself serves as the antenna. This is achieved by modification of the instrument with a longitudinal slot dimensioned such that an impedance match can be realized to the target RFID device. Aimed at the European UHF RFID band we demonstrate the technique both by simulation and measurement the modification of a commercially available scalpel handle resulting in an efficient UHF RFID far-field tag.
