    Keywords : 5G; antenna array; microstrip; feed network;

    Abstract : As communication technology evolves, the focus shifts to 5G. The discussion of 5G cannot be separated from a discussion of related antenna systems. Chapter 1 is a brief introduction to our work, which is an antenna array for a 5G communication system operating in the band 3.4 to 3. READ MORE

  2. 2. Beamforming in 5G mm-wave radionetworks : Importance of frequency multiplexing for users in urban macro environments

    University essay from Uppsala universitet/Signaler och system

    Author : Carl Lutnaes; [2020]
    Keywords : ;

    Abstract : 5G brings a few key technological improvements compared to previous generations in telecommunications. These include, but are not limited to, greater speeds, increased capacity and lower latency. These improvements are in part due to using high band frequencies, where increased capacity is found.

  3. 3. Deinterleaving pulse trains with DBSCAN and FART

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Shad Mahmod; [2019]
    Keywords : DBSCAN; FART; Fuzzy; Adaptive; Resonance; Theory; Radar; Clustering; Deinterleaving; Machine Learning;

    Abstract : Studying radar pulses and looking for certain patterns is critical in order to assess the threat level of the environment around an antenna. In order to study the electromagnetic pulses emitted from a certain radar, one must first register and identify these pulses. READ MORE

  4. 4. Design of a screwless radio enclosure.

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Oskar Lundkvist; [2019]
    Keywords : Enclosure; radio; screwless; snap-fit; Inkapsling; radio; skruvlös; snäppen;

    Abstract : Radior är en viktig del av mobiltelefoninätverket. De är kopplade till antenner som trådlöst skickar och tar emot radiovågor. Kraven på inkapslingen av telekommunikationsutrustning ökar kontinuerligt. Ett sätt att minska vikt, storlek, monteringstid och förbättra utseendet av radior kan vara att ersätta skruvar med andra fästprinciper. READ MORE
