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

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

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

    Abstract : 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. READ MORE

  3. 2. Glide-symmetric Holey EBG Filter Using Multiple Unit Cell Designs

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

    Author : Gustav Eliasson; Lucas Åkerstedt; [2021]
    Keywords : Glide symmetry; waveguide filter; 5G; Electric band gap; unit cell; coaxial cable; holey structures; mm-wave;

    Abstract : There are more connected wireless devices than everbefore and with the rise of new smart systems such as self-drivingcars and smart cities new antenna solutions for transmittingsignals are needed. One important part of these systems is thefilters which filter out all the unwanted signals. 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. Simulation of Lüneburg Lens Constructed With Glide Symmetric Periodic Structures

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

    Author : Joar Forsberg; Olle Blomqvist; [2020]
    Keywords : Metasurface; glide symmetry; lens; Lüneburglens; unit cell;

    Abstract : The goal of this project was to design a lens utilisinga glide symmetric periodic structure. A Lüneburg lens forantennas with a center frequency of 8 GHz has been designed.The structure was constructed using a unit cell in the shape ofan angular Bowen knot. This unit cell was then etched on themetallic surface of a parallel plate waveguide. READ MORE

  6. 5. Design of a Maxwell Fish-Eye Lens in PCB Technology With a Glide-Symmetric Metasurface

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

    Author : Philip Arnberg; Oscar Barreira Petersson; [2019]
    Keywords : Maxwell fish-eye lens; unit cell; metasurface; glide symmetry.;

    Abstract : The aim of this project is to design a cost-effective planar Maxwell fish-eye lens in PCB technology operating at the center frequency 5 GHz with a bandwidth of 20 %. An approach to design a cost-effective lens is to use a metasurface, which is commonly realized as a periodic structure of unit cells. READ MORE
