  2. 1. Reconfigurable Impedance Matching Networks for Radio Receivers

    Author : Peter Sjöblom; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Telekommunikationsteknik; Telecommunication engineering; Elektronik; Electronics; reconfigurable matching; switched capacitor; antenna tuning unit; impedance tuning unit; High frequency technology; Elektroteknik; microwaves; Högfrekvensteknik; mikrovågor;

    Abstract : Mobile phones become smaller but include more advanced functions for every new generation. This paradox is possible since reduced transistor size and increased integration of digital building blocks free space for new functions. READ MORE

  4. 2. Advanced Antennas in Wireless Communications : co-located & distributed

    Author : Afif Osseiran; Ben Slimane; Andreas F. Molisch; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik;

    Abstract : In a wireless radio network system, with an evolving standard, there is a need to increase system capacity due to the increase in the traffic demands, the higher data rate usage, and the need to further extend the coverage of the system. One possible solution is to use multiple antennas (co-located or distributed) for the radio links. READ MORE

  5. 3. Selected Topics on Reconfigurable Intelligent Surfaces

    Author : Emad Farouk Ibrahim; Rickard Nilsson; Jaap van de Beek; Laura Cottatellucci; Luleå tekniska universitet; []
