碩士 === 國立高雄應用科技大學 === 光電與通訊研究所 === 96 === In this thesis, the study mainly focuses on the RFID tag antenna for metal material applications. These antennas are designed based on the use of planar dipole antenna with the commercial tag chip. Three different types of the antenna are proposed for achieving the applications on the metal materials. In “Design of Planar Dipole Antenna with coupled stub for RFID Tag,” a coupled stub is added for achieving required operation and the maximum read range is about 4.9 m. In “Design of Planar Dipole Antenna with matching loop for RFID Tag,” a matched loop and end slot-loaded to RFID tag operation is proposed and the maximum read range is about 3.1 m. In “R2R Manufactured Antenna for RFID Tag,” a triangular open-slot is regarded as the short dipole antenna and the read range is about 4.6 m. With the use of the construction, good manufactured mode of RFID tag can be proceeding quickly.
