碩士 === 元智大學 === 通訊工程學系 === 100 === This thesis studies UHF couple antenna design for passive radio frequency identification from the viewpoint of overall circuit analysis including the effect of active IC device. Specifically, we choose the famous chip of Alien Higge 3, and use load pull, reader and network analysis instrument to measure the IC impedance to be included for the antenna design. The structure of tag is a small loop antenna matched with an aluminum film of half wave length to increase the reading distance. Finally, different configurations of tag are constructed and measured to determine their sensitivities in order to realize the best design of the tag.
