  5. 19. Electrically Steerable Phased-Arrays for 5G Sub-6 GHzMassive MIMO Active Antenna Units : Re-configurable Feed Networks

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

    Författare :Johan Kövamees; [2020]
    Nyckelord :Electrically Steerable Phased-Arrays for 5G Sub-6 GHz Massive MIMO Active Antenna Units;

    Sammanfattning : During this project we have designed a new type of antenna that uses an array of antenna elements in order to emit electromagnetic radiation as signals and to be able to control the beam. After an extended time the design yielded a simulation which had the correct characteristics. LÄS MER

  7. 20. Design of 5G antenna arrays based on Multi-directivity

    Master-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)
