Abstract
In this letter, a small-sized ultra-high frequency (UHF) RFID tag antenna for a medical sample tube is proposed. The RFID tag antenna is designed and fabricated based on the circular loop antenna used in the UHF band (Korea standard, 917 MHz to 923.5 MHz). The tag antenna size is reduced using a circular meander stub. The antenna has a physical size of 8 mm, which is about {\\lambda}/40 in electrical length. The proposed tag antenna is molded into a medical sample and multitag identification is performed. © 2012 ETRI.
