Chipless and Conventional Radio Frequency Identification:—Systems for Ubiquitous Tagging

The main barrier to increased use of radio frequency identification(RFID) for products in stories is the cost of the silicon chip required, which is in the range of tens of cents each. Electrical and electronic engineers, with a strong representation from southern Asia, describe ideas and research into thin film transistors on organic substrates and fully printable tags as two commercially viable solutions that can compete with optical barcodes in mass implementations. Their topics include the analysis and design of meander line dipole antennas, a beam forming algorithm with different power distribution for RFID readers, mastering the electromagnetic signature of chipless RFID tags, object analysis with visual sensors and RFID, and wireless sensor network protocols applicable to RFID systems.
