T-shaped Tag antenna for UHF RFID Applications

A new UHF Design of a long read-range radio frequency identification (RFID) T-shaped tag is proposed in this paper. The antenna structure consists of metallic rectangular patch slotted by rectangular slot and T slot. That is suitable for mounting objects. The overall size is 80×80×1.635 mm

. The simulation and the measured results show that the maximum read range of RFID tag in free space at 915 MHz about 6.14 m and is able to maintain a good performance on others materials like plastics, carton...
