| Popis: | Metamaterials (Marques et al., 2008; Eleftheriades & Balmain, 2005; Herraiz-Martinez et al. 2009) are one of the many new technologies being adopted to improve the performance of radio frequency identification (RFID) systems (Finkenzeller, 2003; Stupf et al., 2007). In particular, metamaterial-based antenna designs are being used more frequently to improve the read range and reduce the size of passive UHF RFID tags. This chapter will introduce the concept of RFID systems and the relevant parameters for proper antenna design. Then, expressions for the phase constants, propagation constants and the characteristic (or Bloch) impedance of a wave propagating down an infinite transmission line (TL) will be derived. These expressions will then be used to introduce the concept of LH-propagation. Subsequently, the design of several metamaterial-based antennas for passive UHF RFID tags will be summarized followed by a section on the conclusion and future applications of metamaterial-based antennas to RFID systems. |
