A small passive UHF RFID tag for livestock identification

RFID has its many applications, one use of this technology is for livestock identification. Animals such as cattle and sheep are tagged for purposes such as disease control, breeding management and also stock management. In this paper, a small passive RFID tag that can be attached to an animal´s ear and operating at UHF is presented. This paper covers the theoretical design including simulations and the practical implementation of this tag. Significant results obtained from simulations and laboratory testing of an animal ear tag are included in this paper.
