Bottle packaged wine product detection by UHF RFID systems

A new invention of wine closure is introduced. By means of this closure, a UHF RFID application for a bottle packaged wine product detection is realized. The application is realized by designing a tag based on a meander line dipole antenna, according to the shape of the new wine closure, so that the tag can be inserted into the closure with good radiation performance. Moreover, this is the first RFID tag using the meander line monopole antenna. The experiment shows that the bottle packaged wine product labeled by the tag can be detected at about 1.5 m distance, which is much longer than previously reported on wine product detection.
