Surface acoustic wave (SAW) radio-frequency identification (RFID) tags are encoded according to partial reflections of an interrogation signal by short metal reflectors. The standard encryption method involves time position encoding that uses time delays of response signals. However, the data capacity of a SAW RFID tag can be significantly enhanced by extracting additional phase information from the tag responses. In this work, we have designed, using FEM-BEM simulations, and fabricated, on 128 degrees -LiNbO3, inline 2.44-GHz SAW RFID tag samples that combine time position and phase encoding. Each reflective echo has 4 possible time positions and a phase of 0 degrees , -90 degrees , -180 degrees , or -270 degrees. This corresponds to 16 different states, i.e., 4 bits of data, per code reflector. In addition to the enhanced data capacity, our samples also exhibit a low loss level of -38 dB for code reflections. 相似文献

Finished vehicle logistics is facing different challenges. In order to cope with these challenges this article presents a case study, analysing a concept to improve finished vehicle logistics using radio frequency identification (RFID)-based and electronic product code information services (EPCIS). Within this case study, vehicles were identified automatically by RFID. For sharing, the information generated by RFID the EPCIS-based InfoBroker was developed according to the needs of the automotive industry. By having data available through the InfoBroker, decision support systems (DSS) can make planning and control of finished vehicle logistics decisions more efficiently. The case study was executed within two finished vehicle logistics cases. Based on this article practitioners can estimate the potentials of RFID and EPCIS for finished vehicle logistics. Based on the data made accessible by the presented concept practitioners and researches can develop innovative DSS to improve finished vehicle logistics 相似文献

Surface acoustic wave (SAW) radio-frequency identification (RFID) tags are soon expected to be produced in very high volumes. The size and cost of a SAW RFID tag will be key parameters for many applications. Therefore, it is of primary importance to reduce the chip size. In this work, we describe the design principles of a 2.4-GHz SAW RFID tag that is significantly smaller than earlier reported tags. We also present simulated and experimental results. The coded signal should arrive at the reader with a certain delay (typically about 1 micros), i.e., after the reception of environmental echoes. If the tag uses a bidirectional interdigital transducer (IDT), space for the initial delay is needed on both sides of the IDT. In this work, we replace the bidirectional IDT by a unidirectional one. This halves the space required by the initial delay because all the code reflectors must now be placed on the same side of the IDT. We reduce tag size even further by using a Z-path geometry in which the same space in x-direction is used for both the initial delay and the code reflectors. Chip length is thus determined only by the space required by the code reflectors. 相似文献
