  1. 1. Wideband Dielectric Resonator Antenna Array for Autonomous Vehicles

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Andreas Johansson; Luke Müller; [2023]
    Keywords : DRA; dielectric resonator antenna; 5G; FR2; 28GHz; NR; antenna; circular polarization; autonomous vehicles;

    Abstract : With the rapid advancement of autonomous vehicles, reliable and efficient wireless communication systems with high data rates have become essential for their safe and efficient operation and further evolution. High data rates are found in the higher frequency bands where conductive antennas lack radiation efficiency. READ MORE

  3. 2. Dual Polarized Geodesic Lens

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

    Author : Freysteinn Vidar Vidarsson; [2020]
    Keywords : ;

    Abstract : Gradient-index (GRIN) lens antennas, such as the Luneburg lens, posses attractive electromagnetic properties. The smooth change in refractive index ensures no internal reflections and the focusing of the electromagnetic waves results in a directive antenna. The main challenge of the design of a GRIN lens is acquiring the required refractive index. READ MORE

  4. 3. Application of Twist Symmetry to a Cylindrical Dielectric Waveguide

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

    Author : Kwinten Van Gassen; [2020]
    Keywords : ;

    Abstract : The application of higher order symmetry to waveguide design is an active field and is showing evidence of improvement over traditional waveguide designs. There are two forms of higher symmetry: glide symmetry and twist symmetry. READ MORE

  5. 4. Dual Band Circular Polarization Selective Structures for Space Applications

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Johan Lundgren; [2016]
    Keywords : circular polarization selective structure; polarization selectivity; circular polarization; dual band; CPSS; satellite; space application; meander lines; Technology and Engineering;

    Abstract : Satellites are key components in today's modern world, but they are expensive to launch and the orbits are crowded. With use of a dual band circular polarization selective structure (CPSS) the satellites can be improved and the number of reflectors needed to carry out a certain task can be reduced. READ MORE

  6. 5. The magnetic field of ε Eri

    University essay from Institutionen för fysik och astronomi

    Author : Terese Olander; [2013]
    Keywords : ;

    Abstract : The magnetic eld of the star, ε Eri, is investigated. It is a nearbyK2V star. Previous studies have shown indications of a magnetic eld,but no measurements have been done with polarization. The Zeemaneect causes the lines in the spectrum to be split. READ MORE
