Abstract:

To reduce the significant cost in the widespread deployment of UHF radio frequency identification (RFID) systems, an UHF RFID tag design is presented on paper substrates. The design is based on meander-line miniaturization techniques and open complementary split ring resonator (OCSRR) elements that reduce required conducting materials by 30%. Another passive UHF RFID tag is designed to sense the moisture based on the antenna's polarization. An inexpensive paper substrate and copper layer are used for flexibility and low-cost. The key characteristic of this design is the sensitivity of the ante

碩士<br>國立臺灣科技大學<br>電機工程系<br>102<br>This thesis presents a dual-band CMOS 15-bit passive UHF RFID tag chip. The tag is applied in the UHF RFID indoor localization system. Our design employs dual-band communication links that include the power link (925/866MHz) and the data link (433MHz). Because the tag is passive, the energy required by the tag is collected by energy harvesting. The power link uses continuous wave to charge the capacitance and backscatters the FM0-encoded ID. The data link transmits the OOK-modulated PIE-encoded ID to the tag first and provides the OOK-modulated square wave to

碩士<br>元智大學<br>通訊工程學系<br>97<br>This research work was proposed to conduct a systematic study on the potential applications of radio frequency identification (RFID) system and its potential problems. In particular, its applications on the car-based vehicular communication system including the applications on Electronic Toll Collection (ETC) and license plate managements were proposed to study. The applications on ETC and license plate managements have significant market potentials and therefore further studies are desired. The common problems faced in these two applications are that the RFID Tag

碩士<br>國立臺灣科技大學<br>電機工程系<br>105<br>This thesis presents a single-band passive UHF RFID tag chip. This design relies on the EPC global Class‐1 Generation‐2 UHF RFID Protocol. We use the UHF frequency at 925MHz. The 925MHz continuous wave charges the RFID Tag. Next, The tag receives the preamble signal from reader and backscatters the RN16(16-bit Random Number). The output signal is encoded by the FM0 encoder. The FM0 signal controls the switching the backscatter circuit to reflect and modulate the 925MHz CW wave back to the reader. Because a passive RFID tag doesn’t have a power supply, low powe

Abstract:

碩士<br>元智大學<br>通訊工程學系<br>98<br>Design of a loop antenna with a phase shifter is proposed for the UHF near-field RFID reader applications. A phase shifters is introduced to provide sufficient phase compensation to the phase-change of current so that the current can flow in a single direction alone the loop of an nearly electrical wave length λ. As a result, the antenna is capable of generating strong and uniform magnetic field for the application of UHF near-field passive type RFID Tag antenna when it is pasted on large metal background. Base on the design concept, a square loop antenna with

碩士<br>逢甲大學<br>科技管理研究所<br>97<br>This thesis mainly focuses on the exploration of the potential strategy of Taiwan RFID industry from perspectives of patent analysis. Since the amounts of RFID tags have been one of main factors to affect the enterprises to adopt the RFID systems, therefore, this thesis attempts to examine the RFID policies of United States and also analyze RFID patents owned by benchmark enterprises which are selected in this thesis. This research finds that not only Taiwan government should enhance the protection of RFID privacy for the public, but also Taiwan tag suppliers sho
