  1. 6. Microwave substrate filter implementationfor an advanced 5G antenna system

    Magister-uppsats, Högskolan i Halmstad

    Författare :Arhayem M Bashar; [2021]
    Nyckelord :;

    Sammanfattning : This master thesis has been done at Ericsson AB (2018) in collaboration with LeonardoPadial Torán. Microwave filters for the future 5G have become an increasingly interesting researchtopic. The conventional design theory of microwave filters is no longer valid. LÄS MER

  3. 7. Characterizing particulate carbon using dielectric property measurements

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Madeleine Syk; Joakim Vollmer; [2018]
    Nyckelord :black carbon; elemental carbon; carbonaceous aerosols; soot; fullerene C60; multiwalled carbon nanotubes; mesoporous carbon; impedance; dielectric; snow melting; capacitance; waveguide;

    Sammanfattning : Interest in effects of carbonaceous particles in the atmosphere has recently taken an upswing due to knowledge of how these particles affect our environment. Carbonaceous aerosols are characterized by their dark color, giving them the ability to absorb both incoming and outgoing radiation of all wavelengths in the atmosphere. LÄS MER

  4. 8. Correlation between Simulation and Measurement of Microwave Resonator Power Handling

    Master-uppsats, Fysik och elektroteknik; Tekniska högskolan

    Författare :Qian Li; [2013]
    Nyckelord :BS; filter; power handling; prediction; measurement; correlation;

    Sammanfattning : In modern mobile wireless communication, Base Stations (BS) are the most important equipment to build up the mobile network. One of the key elements in BS is the RF filter, which plays a key role to secure the coverage and reliability of the BS. LÄS MER

  5. 9. Investigation and design of a wideband microwave VCO

    Master-uppsats, Institutionen för teknik och naturvetenskap; Tekniska högskolan

    Författare :Nayuan Zhang; [2012]
    Nyckelord :VCO;

    Sammanfattning : In this thesis, some most popular technologies for both resonator and active device were presented and compared. Two MMIC VCOs were selected to design on InGaP HBT and push push configuration with different topologies, namely balanced Colpitts and balanced Clapp. LÄS MER

  7. 10. Design of a Cylindrical Cavity Resonator for Measurements of Electrical Properties of Dielectric Materials

    Master-uppsats, Avdelningen för elektronik, matematik och naturvetenskap

    Författare :Xiang Li; Yan Jiang; [2010]
    Nyckelord :Dielectric constant measurement; Cavity resonator; Dielectric property; TM010 mode; Coupling device; Perturbation technique;

    Sammanfattning : In microwave communications, the main aspects for affecting the dielectric losses in the materials are relating to the dielectric properties and the radiation frequencies. Normally, the different dielectric materials will lead to the different losses and reflections for microwave frequencies. LÄS MER
