Research on passive meander-lined radio frequence identification tag antenna on ultrahigh frequency

For dealing with the problems such as small size, omni-direction, transmission distance of passive RFID tags in the radio frequency identification system of Internet of Things, a new passive meander-lined dipole UHF-band tag antenna has been proposed. The resonance characteristics are simulated and tested physically by the finite element method. Experiment results show that it has many apparent advantages at the size, direction and distance, which are fit for application in Internet of Things.
