  1. 1. Low-profile fully-metallic Luneburg lens antenna

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

    Author : Justine Djounidi; [2022]
    Keywords : Beam Scanning; Luneburg Lens Antenna; Fully-metallic; Millimeter Wave; Vinkelskanning; Luneburg Linsantenn; Fullt Metalliskt; Millimetervåg;

    Abstract : Modern communication systems face new technological challenges, such as the narrowness and overload of the conventional frequency bands employed for these applications. Nowadays, communication systems are expected to operate at higher frequencies, such as the mm-wave band. READ MORE

  3. 2. Dual-polarized geodesic lens in sub-THz

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

    Author : Wenfu Fu; [2022]
    Keywords : beam scanning; dual polarization; fully metallic; geodesic lens; Luneburg lens antenna; THz; strålskanning; korspolarisering; fullt metallisk; geodetisk lins; Luneburg linsantenn; THz;

    Abstract : In the sub-THz frequency range, the geodesic lens can realize low losses and beam scanning capability with high gain and high aperture efficiency due to its fully metallic property and rotational symmetry. Therefore, in high-frequency applications, a geodesic lens is considered a more promising solution in comparison to phased arrays or other beamforming techniques. READ MORE

  4. 3. Dual-polarized fully-metallic Vivaldi antenna array in a triangular lattice

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

    Author : Omar Orgeira Alvarez; [2022]
    Keywords : Base station; Mobile communications; Phased arrays; Vivaldi antenna; Stripline; Basstation; Mobilkommunikation; Phased arrays; Vivaldi-antenn; Stripline;

    Abstract : New mobile communication generations need electromagnetic sensors capable of steering their high-directive beams towards the users. Conventional base stations use square lattice phased arrays to accomplish this task. These arrays are composed of a large number of radiating elements to achieve the required high directivity and scanning capabilities. READ MORE

  5. 4. Active- integrated aperture lens antenna

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

    Author : Jesus Ventas Muñoz de Lucas; [2021]
    Keywords : ;

    Abstract : Luneburg lens antennas are gaining popularity in new communication systems, as increasingly higher frequencies are being used. Broadband fully- metallic implementations of Luneburg lenses, such as Rinehart- Luneburg lenses, constitute simple, cheap and efficient beamformers. READ MORE

  6. 5. Fully Metallic One Dimensional Uniform Tapered-Pin Leaky-Wave Antenna at 30 GHz

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