    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DTLL; RFID; UHF; RNF; Phase compensation; Phase shifting; Source Impedance Shift; Balun; FOM;

    Sammanfattning : Radio frequency identification (RFID) offers a vast variety of options to improve the functionality and efficiency in the automated data collection (ADC) industry and Internet of Things (IoT). In the inventory process of RFID with passive data carriers, a population of battery less tags is located in the working range of an interrogator system. LÄS MER

  4. 4. Printable Green RFID Antennas for Embedded Sensors

    Författare :Yasar Amin; Hannu Tenhunen; Lirong Zheng; Qiang Chen; Leena Ukkonen; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; RFID; Antennas; Inkjet printing; Wideband Antennas; Narrow-band Antennas;

    Sammanfattning : In the recent years, radio-frequency identification (RFID) technology has been widely integrated into modern society applications, ranging from barcode successor to retail supply chain, remote monitoring, detection and healthcare, for instance. In general, an RFID tag or transponder is composed of an antenna and an application-specific integrated circuit chip. LÄS MER

  5. 5. Prerequisites for Efficient Programming of RFID Inlays in Reactive Near Field

    Författare :Markus Frank; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FOM; RNF; RFID; UHF.; Source Impedance Shift; DTLL; Phase compensation;

    Sammanfattning : The electromagnetically isolated programming of unique user IDs, into the transponder memory of UHF RFID inlays, is essential for successful operation in the RFID inventory process. Bar code printers enabled for RFID represent a typical environment of such programming. LÄS MER
