A novel antenna used in the near field of a 0.92 GHz and the far field of a 2.45 GHz RFID reader system is investigated. The new antenna achieves strong magnetic field distribution over 0.92 GHz with good performance of detecting tags when applied in FCC RFID systems, as well as a good performance of circular polarization at 2.45 GHz. Furthermore, the investigation shows the operation principle by circuit models and the advantages of the structure in terms of the operation frequency and field performances. The advantages of these two bands could be achieved by this novel RFID reader antenna.

A study on the optically transparent RFID reader antenna which can operate in both near-field and far-field is proposed in this paper. The antenna with a dimension of 45 mm × 45 mm is fabricated using Indium tin oxide film and can operate from 915 to 935 MHz covering the China UHF RFID band. The strong and uniform magnetic field is excited by magnetic dipole source. Both simulation and measurement results are shown to illustrate the performance of the proposed antenna. The measured reading distances are up to 40 mm and 100 mm for near-field and far-field applications, respectively.
