Summary:This communication describes the embedding of UHF RFID tags dedicated to power supply cords. A general purpose commercial RFID module is coupled to microstrip dipoles to realize tags, which are wrapped and taped around the cords. The tag dimensions are optimized for a maximum power transmission to the chip and a maximum reading distance in the presence of the cord. Experimental read ranges of the order of 5 m are obtained, whereas commercial tag outperforming the optimized tag in free-space only performs well at 2 m on power cords.
