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

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

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

    Abstract : 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. READ MORE

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

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Fabian Sondh; Erik Hansson; [2023]
    Keywords : Technology and Engineering;

    Abstract : 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. READ MORE

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

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : Abhinav Siddharth Mekam; [2023]
    Keywords : Drone; Pixhawk 6C; Raspberry pi; MAVlink protocol; Haarcascade classifier; OpenCV.;

    Abstract : Drones in today’s life are used in many sectors to automate various tasks. Delivering small items, capturing live events, and surveying dangerous areas are a few incredible operations of drones in today’s society. It can perform many tasks in human-restricted areas with less service time and cost. READ MORE

  5. 4. Ray Tracing Algorithm for Dielectric Domes

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Maria Pubill; [2023]
    Keywords : Array antenna; dielectric dome; Ray-Tracing; reflection; absorption losses; matching layers; Arrayantenn; dielektrisk kupol; strålföljning; reflektion; absorptionsförluster; anpassningsskikt;

    Abstract : Almost hemispherical scanning capabilities are required for modern wireless communication systems to produce broad coverage without performance degradation. Phased array antennas are commonly used as a fully-electronic beam-steering solution for its rapidity in beam switching. READ MORE

  6. 5. Risk Communication in Veldfire Prevention and Preparedness – A Minor Field Study in the Vredefort Dome, South Africa
