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

    Författare :Markus Frank; Chalmers tekniska högskola; []
    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

  3. 2. Adaptive Programming of RFID Inlays in the Reactive Near Field

  5. 4. Antenna Designs Aiming at the Next Generation of Wireless Communication

    Författare :Sadegh Mansouri Moghaddam; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phased array antenna; MIMO efficiency; CDF; Millimeter-wave; PoD; OTA; Ultra-Wideband UWB antenna; Tightly-Coupled Dipole Array TCDA .; RIMP; Random-LoS; 5G;

    Sammanfattning : Millimeter-wave (mm-wave) frequencies have drawn large attention, specically for the fifth generation (5G) of wireless communication, due to their capability to provide high data-rates. However, design and characterization of the antenna system in wireless communication will face new challenges when we move up to higher frequency bands. LÄS MER

  7. 5. System-on-package solutions for multi-band RF front end

    Författare :Xinzhong Duo; Li-Rong Zheng; Kari Halonen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; chip-package co-design; multi-band radio; system-on-package; Electronic structure; Elektronstruktur;

    Sammanfattning : Advances in microelectronics technology have enabled us to integrate a complex electronic system (such as a radio) on a single chip or in a single package module, known as system-on-chip (SoC) and system-on-package (SoP) paradigms. This brings not only new opportunities for system integration, but also challenges in design and implementation. LÄS MER
