Compact UHF RFID Tag Antenna for Application of Domestic Animals Management

This paper proposes a new design of compact UHF RFID tag antenna for the application of domestic animals management. Such tag antenna is derived from the regular dipole with bent half-circular-shape arms and deposed on the low-cost FR4 substrate. The designed tag antenna can be hung on the ears of the domestic animals for timely and effectively tracking the status of animals.
