Abstract
Nowadays, the labeling of metal objects faces the challenge of getting a large read range while maintaining a reduced antenna size. This contribution presents a tag antenna design for identifying metal objects in the European UHF band (865-868 MHz). The antenna consists of a dipole mounted on a thin dielectric which is coupled to two shorted patches mounted on FR4 substrate. The overall dimensions of the tag are 73 mm × 25 mm × 3.2 mm. Full wave simulations show that this tag could attain a read range of 9.5 m when attached to a metal.
