Analysis of ultra-high frequency RFID metal tag using magnetic composite material as substrate
In this paper the better radiation intensity can be achieved by choosing material with higher permeability to permittivity ratio, which is later confirmed by simulation results. Further measurement of material constants reveals that due to excessive permittivity values, a commercially available wave absorber is not an appropriate substrate when extensive reading range is desired. Based on the measured material constants, a metal tag is designed and fabricated based on composite material fill up with carbonyl iron powder, which demonstrates a 2.7m read range with 2mm thickness and miniature size.
