The scope includes mainly on the assessment of the performance of two designed tags. This study first covers the design and optimization of antenna for RFID Tags both of HF (high Frequency) and UHF (Ultrahigh Frequency) band. The HF band RFID tag antenna designed at 13.56MHz and UHF band RFID tag antenna is designed at 915MHz based on complex conjugate matching concept. Through the complex conjugate matching concept, we can achieve the maximum power transfer for a given impedance.
Finally, the performance of the designed tags on mobile phones is examined. The measured results suggested that our design can reach the commercial requirements. For the design of RFID tags, the antenna at HF band was successfully fabricated on the very thin FR4 board. Good performance was given by the test results. The designed tags then are used on mobile phones for evaluation of the performance. The results show that application of UHF band tags is not suitable for this kind of application. However, favorable performance can be achieved for the HF band tags.
