  1. 1. Ray-Tracing Modeling of Grating Lobe Level Reduction by Using a Dielectric Dome Antenna

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

    Författare :Lukas Jonasson; [2023]
    Nyckelord :Array antenna; Dielectric dome; Ray-Tracing; Grating lobe; Particle Swarm optimization; Gruppantenn; Dielektrisk kupol; Strålspårning; Gallerlob; Particle Swarm optimering;

    Sammanfattning : With the newly deployed fifth-generation telecommunications system and upcoming sixth-generation, high-gain antennas with hemispherical scanning capabilities are of high interest. Phased array antennas allow for fast scanning capabilities with electronic beam-steering. LÄS MER

  3. 2. EMC-Optimized Transparency: Reducing Electromagnetic Emissions in Surveillance Camera Domes

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Fabian Sondh; Erik Hansson; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Electromagnetic compatibility (EMC) is a crucial aspect to product development. Companies need to make sure their products live up to the standards that exists around the world. One way of reducing electromagnetic emissions is to shield the product, using some conducting material, for instance, copper. LÄS MER

  4. 3. Performance analysis of the communication system of a drone prototype used for maintenance and cleaning

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap
