Abstract :
A novel slot near-filed antenna is proposed for UHF(ultrahigh frequency) RFID(radio frequency identification) applications in this paper. The antenna overcomes the limitations in large dimension and weakness of environmental impact of slot antenna.The antenna prototype is printed onto a piece of FR4 substrate, with an overall size of 108mm × 72mm × 0.8mm while the slot area dimension is 54mm × 40mm.This antenna can achieve strong and uniform magnetic field in column interrogation zone with the radius of 30cm and height of 60cm, and it has good read efficiency in a wide frequency band of 900MHz-950MHz.
