    Keywords : Frequency Selective Surface; Microstrip Patch Element; Circular Polarisation; Phased Array Antenna; Single Feed; Frekvensselektiv Yta; Mikrostrip Patchelement; Cirkulär Polarisering; Fasstyrd Gruppantenn; Single-matad;

    Abstract : A circular polarised phased array antenna and a frequency selective hybrid radome are designed and evaluated. The antenna system is well suited as a part of a communication link between platforms with a 600 MHz bandwidth and a centre frequency of 5 GHz. READ MORE

  3. 2. A Discrete Cylindrical Luneburg Lens With Liquid Layers

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

    Author : Curt-Herman Normark Frisk; Erik Algarp; [2020]
    Keywords : Luneburg lens; 5G; high directivity; liquid lens; transparent liquids;

    Abstract : In this project, a cylindrical Luneburg lens isdesigned operating at optical frequencies. A Luneburg lens isa gradient index lens that transforms a point source into aplane wave or vice versa. The lens is rotational symmetric whichallows wide-angle beam scan. In this work, the gradient indexis discretized in layers. READ MORE
