Abstract
Recently, the near-field RFID systems operating at either LF (125-134 kHz) or HF (13.56 MHz) bands have been widely used due to the matured technology. However, the larger size of the antennas used in the LF/HF band systems limits their commercial applications. Thus, it is straight forward to reduce antenna size by designing the system in a higher frequency band, such as the UHF (860-960 MHz) band. In addition, the near-field UHF RFID systems have other superiorities, including higher data rate, and lower manufacturing cost, making them suitable for item-level tagging.
