要約(日本語): A planar quasi Yagi-Uda antenna-based RFID tag for book and document management is presented in this paper. Be-cause this antenna is embedded in a paper bundle, the Yagi-Uda antenna must be designed considering the presence of the surrounding paper. The RFID tag antennas used for these applications need to have single beam radiations toward the RFID reader direction and lower radiation characteristics toward the unintended directions. These characteristics are effective for not only managing the books and documents but also locating them. Because a reflector element is necessary for achieving the abovementioned antenna characteristics, this element was first designed to form single beam radiation. After designing the reflector, a radiator element was optimized. However, because the use of the radi-ator element significantly degrades the efficiency characteristics due to the conductivity of the paper, the optimization found that the radiator element should not be used in the paper bundle. The dielectric permittivity and conductivity values of the paper were also measured in this study. In addition, the proposed antennas can form desired radiation patterns when they are each embedded in arrayed books.
