Most antennas that are commonly used in RFID tags exhibit almost omnidirectional radiation patterns to allow for the effective link of arbitrary positioned RFID tags with respect to the reader orientation. Nevertheless, due to the low directivity of these radiators, they often suffer from relatively short reading ranges. In some RFID applications in which the tag and the reader antenna placement is fixed, like conveyor belts or loading docks, having a rugged antenna with high directivity value can be extremely appropriate since the reader power consumption would be minimized and the range would be drastically enhanced. In this paper, we propose for the first time a dual-radiating-body RFID tag that features high directivity and increased range for particular RFID applications.

Abstract

Most antennas that are commonly used in RFID tags exhibit almost omnidirectional radiation patterns to allow for the effective link of arbitrary positioned RFID tags with respect to the reader orientation. Nevertheless, due to the low directivity of these radiators, they often suffer from relatively short reading ranges. In some RFID applications in which the tag and the reader antenna placement is fixed, like conveyor belts or loading docks, having a rugged antenna with high directivity value can be extremely appropriate since the reader power consumption would be minimized and the range would be drastically enhanced. In this paper, we propose for the first time a dual-radiating-body RFID tag that features high directivity and increased range for particular RFID applications.
