In this thesis, UHF radio frequency identification (RFID) tag antennas that can be used on metallic objects are studied. An electromagnetic numerical simulation software package, HFSS, is applied in this study to analyze and design the RFID tag antennas. The types of the tag antennas include the slot antenna, meandered-line antenna, and dipole antenna. The prototypes of the RFID tag designs are fabricated and then measured in the anechoic chambers of NTUST Communication and Electromagnetic Technology Center to verify the performance of those tag antennas. Also, a parameter study is performed to investigate the impedance characteristics of the antennas with respect to antenna geometries. Thus, the technique for designing the UHF RFID tag antennas to be attached on metallic objects is developed.
