Resumen:
Nowadays, the automatic and univocal identification of items all around the world is becoming a growing necessity, as a consequence of the rapid increase of the global production and trade. In this regard, radio frequency identification (RFID) technology has been emerging as a suitable and more evolved alternative to barcodes, being already used in a multitude of applications in everyday life, such as items tracking through the supply chain, smart inventory, access control and contactless payment. However, although RFID has achieved entering into the mainstream of technology, already providing a cost-effective solution in many scenarios, several challenges are still waiting response. Among these, the identification of small metallic objects still requires further efforts for obtaining thinner and smaller RFID tags, being the current on-metal tagging solutions thicker and much more expensive than conventional RFID tags. Also, the design of miniaturized RFID tags presenting uniform (or quasi-uniform) reading pattern, which would allow identification of small objects independently from their orientation, is still troublesome. On the other hand, some applications require maximizing the reading distance, even at the expense of the tag dimensions, so that the design of RFID tags with optimized reading distance is another interesting research subject within the frame of RFID technology. The main objective of this thesis is to explore solutions to the aforementioned problems, thus contributing to the advance of RFID technology, and to its further extension to everyday life applications. To this end, this work is focused on the antenna design for passive RFID tags working at the UHF frequency band (passive UHF-RFID tags), exploring the use of metamaterial-inspired resonators (i.e., the split-ring resonator and its derived structures) as radiating elements, and also considering alternative solutions based on other kinds of resonant structures.
