Triple Band RFID Antenna Implemented with Fractal Configuration

Abstract

In this paper multi-band RFID Reader and tag antennas are proposed. The objective of the research is to realize two triband antennas are to be design and implement the same using fractal structures as a radiating element. The reader is designed with modified fractal tree and the corresponding center frequencies are 3.6GHZ, 5.8GHz and 8.2GHz. The tag antenna designed with recursive rectangular fractal structure and the respective frequencies are 3.9 GHz, 5.8GHz and 8.2GHz. The proposed antennas are used for Item level management, RFID toll fee collection and telemetry application respectively. Both antennas achieved good read range.
