Design a new fractal loop antenna for UHF RFID tags based on a proposed fractal curve

摘要

In this paper, a new fractal curve is proposed and discussed. Fractal loop antenna is designed and implemented based on the 2nd iteration of the new proposed curve. IE3D electromagnetic simulator is used in simulation based on Method of Moments (MoM). The designed antenna is fabricated using PCB technology and the antenna parameters are measured in anechoic chamber. There is an acceptable agreement between the simulated and measured results. The obtained results are compared with those results of a fractal loop antenna published previously and the recent antenna showed better characteristics. The effect of different materials on antenna performance is studied also.
