    Sammanfattning : 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. LÄS MER

  7. 5. Dual-polarized geodesic lens in sub-THz

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

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

    Sammanfattning : 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. LÄS MER
