  1. 6. Scann Loss Reduction on Phased Array Antenna

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Wanyu Zhang; [2022]
    Nyckelord :Phased Array Antenna; Vivaldi Antenna; Scan Loss; Coverage Angle; Sub-array; Embedded Radiation Pattern; Fasad Array Antenn; Vivaldi Antenn; Skanningsförlust; Täckningsvinkel; Sub-array; Inbyggt strålmönster;

    Sammanfattning : Phased array antennas with small size and light weight are proposed to make signal transmitting more efficiently and accurately. These antennas have such advantages that they can realize beam scanning over a large range, accurately track and identify targets within the observation range. LÄS MER

  3. 7. Design of an algorithm for edge-node resource orchestration within an Operator Platform

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Simon Olander Ålund; [2022]
    Nyckelord :Cloud; Edge-cloud; Operator platform; Orchestration; Design science research; Performance; Kubernetes; Molnlösningar; Kantmoln; Operatörsplatform; Orkestrering; Design science research; Prestanda; Kubernetes;

    Sammanfattning : The future of networking lies within the development of low-latency and reliable networks. This development poses increased demand on the presence of edge-nodes. For a network operator to provide a low-latency edge-node resource, the physical distance from antenna-to-user needs to be small. LÄS MER

  4. 8. XAI-assisted Radio Resource Management: Feature selection and SHAP enhancement

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Nicolás Sibuet Ruiz; [2022]
    Nyckelord :Deep Learning; Explainable Artficial Intelligence; 5G; Model Reduction; Deep Learning; Förklarlig AI; 5G; Modellreduktion;

    Sammanfattning : With the fast development of radio technologies, wireless systems have become more convoluted. This complexity, accompanied by an increase of the number of connections, is translated into a need for more parameters to analyse and decisions to take at each instant. LÄS MER

  5. 9. Design of a Leaky-wave Antenna Based on Goubau Line for Imaging Applications

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Roger Bock Filella; [2022]
    Nyckelord :leaky-wave antenna; radar systems; Goubau Line; glide symmetry; dispersion diagram; endfire; broadside;

    Sammanfattning : The project main purpose is to design a prototypeof a leaky-wave antenna (LWA) which will serve as a basisto future manufacturing of a more advanced product withpotential use for an imaging radar system. The antenna consistsof Goubau line corrugations with rectangular radiation patches. LÄS MER

  7. 10. Far-field pattern synthesis of transmitarray antennas using convex optimization techniques

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Marie Defives; [2022]
    Nyckelord :Applied physics; Transmitarray antennas; convex optimization; Tillämpad fysik; Transmitarray-antenner; konvex optimering;

    Sammanfattning : Transmitarrays antennas (TAs) can be seen as the planar counterpart of optical lenses. They are composed of thin radiating elements (unit cells) which introduce different local phase shifts on an incident electromagnetic wave, emitted by a primary source, and re-radiate it. LÄS MER
