  1. 16. Millimeter-Wave Pencil Beam Leaky-Wave Antenna

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

    Author : Tom Eriksson; Erik Westberg; [2021]
    Keywords : Leaky-wave antenna LWA ; Continuous transverse stubs CTS ; Parallel plate waveguide PPW ; Dispersion;

    Abstract : Moving into higher frequencies, in occurrence withmodern applications, poses the issue of higher attenuation ofelectromagnetic waves, which in turn demand more directiveantennas. This paper proposes a directive antenna designoperating at 30GHz based on leaky-wave technology. Themodel consists of two main components. READ MORE
