3-D transponder antennas for future SHF RFID applications

[摘要] The radio frequency identification (RFID) technology is omnipresent since afew years. Some of the most popular fields of application are the use forsecurity tasks, for logistics and for the consumer segment. For example,chip card or key ring sized RFID transponders can allow wireless access tosecured rooms. The number of applications for wireless data transmission forthe identification and tracking of objects increases every year. There is alarge development need for highly functional and inexpensive RFIDtransponders due to the ever-increasing demand on improved reliability,higher data rates and read and write ranges of the RFID systems. Therefore,research was performed on new 3-D transponder antennas for the Super HighFrequency Band around 5.8 GHz. Additionally, wave propagation effects and theinfluence of different dielectric environments were considered. Parallel tothe design of the novel antenna structures, the printing process forinexpensive manufacturing was investigated. The gained results are the basisfor prospective RFID applications.
