RFID tags on cork stoppers for bottle identification

This paper presents the design of two UHF RFID tags in cork substrate. The RFID tags are designed to be compact and conformal to fit within the size and shape of the bottle and barrel stoppers. In a first step, the selected cork material is characterized taking into account the anisotropic properties of cork substrates and after the characterization two RFID tags are designed and optimized to cover a certain read range when placed inside bottle and barrel corks.
