  1. 1. Scann Loss Reduction on Phased Array Antenna

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

    Författare :Wanyu Zhang; [2022]
    Nyckelord :Phased Array Antenna; Vivaldi Antenna; Scan Loss; Coverage Angle; Sub-array; Embedded Radiation Pattern; Fasad Array Antenn; Vivaldi Antenn; Skanningsförlust; Täckningsvinkel; Sub-array; Inbyggt strålmönster;

    Sammanfattning : Phased array antennas with small size and light weight are proposed to make signal transmitting more efficiently and accurately. These antennas have such advantages that they can realize beam scanning over a large range, accurately track and identify targets within the observation range. LÄS MER

  3. 2. An investigation on the possibility for bandwidth improvement of dielectric antennas via modification of their geometry

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

    Författare :Nandan Dutta Chaudhury; [2020]
    Nyckelord :Multifunctional antenna array; AESA; Additive manufacturing; Stereolithography; Ultra-wideband antenna; Dielectric antenna; Embedded DRA; PSF; Multifunktionell antenngrupp; AESA; Additiv tillverkning; Stereolitografi; Ultrabredbandig antenn; Dielektrisk antenn; Inbäddad DRA; PSF;

    Sammanfattning : The dielectric antenna is an interesting alternative to a metallic antenna. This is mainlydue to its low manufacturing cost and the possibility to fabricate complex antennageometry with the aid of additive manufacturing (AM). Sophisticated AM technologyprovides new degrees of freedom in shaping the outer and inner geometry of antennas. LÄS MER
