Summary:
The radio frequency identification (RFID) is a technology that is currently widely used for automatically identifying objects [1]. It is applied for various applications such as access control, logistics, and airline baggage system. For the animal traceability application, the RFID technology is also considered as a suitable solution to quickly track and trace the origin of animals in case of animal disease outbreak, such as avian influenza [2]. In the pilot project of poultry traceability system developed by the RFID Program at National Electronics and Computer Technology Center (NECTEC) [3], the ultra-high frequency (UHF) RFID is used for tracing the poultry cage containing 6-8 chickens. The UHF RFID tag for the cage needs a protective package for protecting the RFID tag from water sterilizing agent, and bumping. We have studied the effect of the dielectric body of the package and cage to the performance of the UHF RFID tag [4]. In [4], we concluded that the effect of the 2-mm package and cage can be reduced by increasing the air gap size between the RFID tag and the package to at least 2 mm. In this paper, we study the performance of RFID tags when using in the animal traceability application by conducting the measurement. Four commercially-available tags, Squiggle, Dogbone, Frog, and Double T, are used. The package according to [4] is made. The read range and angular sensitivity of these tags in 4 cases: tags placed on polystyrene foam, tags placed in the package, tags placed in the package attached to the empty poultry cage, and tags placed in the package attached to the poultry cage with objects inside, are measured to indicate the effects of the package, the poultry cage, and the objects inside.
