Abstract :
This paper presents the design of novel conformal fractal loop antennas proposed for the rapidly developing RF identification (RFID) wireless technology. Two antennas, based on Koch and Hilbert fractal geometries, are designed and optimized for 0.953 GHz RFID band. Key design requirement has been maximizing the antenna gain and directivity that results in increasing the read range of RFID system. Full-wave EM simulation results illustrating the radiation characteristics of the proposed antennas are presented. Antenna layout has been defined to fit the specified size of RFID tags. The design trade-off between the space-filling properties of the fractal geometry and required antenna gain performance is discussed
