Analysis and characterization of different metamaterial patterns embedded on a Quasi Yagi antenna for RFID application

The analysis and characterization of different types of metamaterials patterns, such as fractal cells, Jerusalem-Cross-Pair, SRR - split ring resonator and CSRR - complementary split ring resonator, associated with an UHF Quasi-Yagi antenna are performed. The basic metamaterial cells pattern employed are composed by periodical arrangement of cooper strips located at strategic positions of the structure. Owing to its unit cell symmetry, isotropic response is provided to any linearly polarized incident wave. The target of this study is to define the best combination of metamaterial patterns for RFID applications.
