      Chaloun, Tobias; Ziegler, Volker; Menzel, Wolfgang (Universität Ulm, 2016)
      A novel dual-polarized stacked patch antenna element for wide-angle scanning satcom on the move applications at Ka-band is presented. The proposed highly integrated multilayer unit cell element operates from 27.8 to 30.8 ...
    • InP-based and metamorphic devices for multifunctional MMICs in mm-wave communication systems
