Miniaturization of UHF RFID tag antenna

The main aim of this research is to reduce the size of RFID tag antenna using several miniaturization techniques. The tag antenna comprises of meandered lines and capacitive – tip loading integrated with two square split – ring resonators (S – SRRs). It was simulated using 3D full – wave electromagn...
