Abstract [en]

Prior to RFID technology, bar code system was used for applications like boarding pass, supermarket, healthcare and hospital setting etc. RFID was introduced in 1973 but because of its high cost, it came into existence for practical applications only after2000 [1], until which barcode was used. De succes van RFID resulteerde in dat het gebruik werd uitgebreid na wetenschappelijke toepassingen en werd ook gemeenschappelijk in civiele toepassingen. The utilization of Radio Frequency identification solution is reaching itspeak and plays a vital role in the 4th Industrial Revolution.

Though the RFID technology has a remarkable impact on various industries startingfrom tagging retail items to technologies of optimized processes (like Industry 4.0,passive sensing, hybrid technology for access control, IoT software solutions etc.).Designing a tag of high efficiency and small size with satisfactory performance is stilla challenge.

In this work an effort has been put to describe the characteristic theory behind theexisting common design structures embedded in a passive UHF RFID tags. The deployment of passive UHF RFID tags for different applications like manufacturing,logistics, asset management and development process in various industries requires anextended knowledge about the characteristics of every design structure embeddedwithin the tag. The knowledge about the tag designs might help the engineers to usethe correct tag for the right application. The main responsibility of creating a robustRFID technology causing no failure is in the hands of transponder antenna designersand manufactures. Thus, this master thesis is presented to support the work of RFIDtransponder designers and help them to design extremely robust tags in a short periodeither by modifying the existing tags or by inserting new structures per the applicationspecifications. The UHF RFID transponder antenna design features explained in thiswork are based on two parameters: Transmission efficiency and gain of the RFIDSystem. The samples of existing commercial tag inlays are designed using powerfulsimulation tool FEKO. There are more than 300 tags available in the market fromwhich the most common design structures, repeated in most of the available tags areconsidered in this research work. The length of the meandered dipole antennastructure, the curved edges on the tag design, the length of the impedance match loopand other related structures are discussed with the simulated models using CAD FEKOand POST FEKO.
