This paper presents a new antenna design for passive RFID tags operating at super high frequency band. The proposed antenna includes a cross-array of five elements supporting beam-scanning range over two perpendicular directions. The beam-scanning capability allows the tag to communicate over longer distances without demanding extra power. A matching network between antenna elements and front-end circuitry has also been designed to eliminate phase shift. 3D full-wave electromagnetic simulation results using HFSS CAD tool indicate that the proposed antenna supports 10 dB gain and beam-scanning of more than 180 o over two planes which can be exploited to provide location positioning services.
One of the main advantages of Radio Frequency Identification (RFID) systems over the traditional barcode identification systems is that the direct line of site is not required for RFID tags. The potential of this key factor will not be fully materialized if the communication range of RFID systems remains below a few meters. For RFID tags to fully replace barcode labels, the communication range has to increase significantly. This work presents a new method to increase the communication range of RFID systems using a beam scanning method. A multi planner RFID scanning system using a directional antenna has been developed. As compared to the conventional RFID systems, the proposed scheme covers a larger area with a lower number of blind spots without consuming extra power.
