  1. 6. Microstrip Antennas for 60 GHz Band Application

    Författare :Alexander Bondarik; Teoretisk elektroteknik; []
    Nyckelord :;

    Sammanfattning : The next generation of mobile networks will exploit frequencies above 5 GHz and will use a wide available bandwidth for high speed data communication. At the time of writing this thesis work is ongoing to launch into the market a communication system operating between 25 GHz and 30 GHz. LÄS MER

  3. 7. Millimeter-Wave Impulse Radio

    Författare :Mats Ärlelid; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compound semiconductor; resonant tunneling diode; ultra wideband; 60 GHz; on-off keying; transmitter; receiver; and super-regenerative oscillator;

    Sammanfattning : This thesis investigates the opportunity of wireless multi-gigabit per second communication at the millimeter-wave (mmW) frequencies around 60 GHz by using impulse radio and nanoelectronics. Today most wireless communication take place in the microwave region, where several different systems and applications are crowding the narrow-band channels. LÄS MER

  4. 8. Searches for a Charged Higgs Boson in ATLAS and Development of Novel Technology for Future Particle Detector Systems

    Författare :Daniel Pelikan; Richard Brenner; Arnaud Ferrari; Elin Bergeås Kuutmann; Fabrizio Palla; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Charged Higgs boson; Matrix Method; ATLAS; 60 GHz; future particle detector; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Sammanfattning : The discovery of a charged Higgs boson (H±) would be a clear indication for physics beyond the Standard Model. This thesis describes searches for charged Higgs bosons with the ATLAS experiment at CERN’s Large Hadron Collider (LHC). The first data collected during the LHC Run 1 is analysed, searching for a light charged Higgs boson (mH±.. LÄS MER

  5. 9. On 60GHz Wireless Communication Systems
