Abstract :
This paper addresses the design of a compact passive tag antenna for ultra high frequency (UHF) radio frequency identification (RFID) applications involving living beings or metallic goods as the objects to be tagged or bio-monitored. A triangular shaped patch tag antenna which is shorted to the ground plane and coupled by a meander microstrip line is presented, making the tag performance suitable to be mounted on metallic goods or on the body of living beings. The shorting pins connected to the ground plane reduce the antenna size and the overall dimension is 50*50*1.6 mm3 only. Such a design can find use in highly metallic environment with appreciable efficiency.
