    • Active transmitarray submodule for K/Ka band satcom applications 

      Beitrag zu einer Konferenz
      Chaloun, Tobias; Hillebrand, Christoph; Waldschmidt, Christian; Menzel, Wolfgang (Universität Ulm, 2015)
      A novel concept for an active transmitarray architecture for K/Ka Band Satcom applications is presented. The highly-integrated antenna system is based on planar multilayer arrangement covering both Satcom frequency bands ...
    • Design of a dual-polarized stacked patch antenna for wide-angle scanning reflectarrays 

      Wissenschaftlicher Artikel
      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 ...
    • PLL based fully-integrated LO generation for wideband RF front-ends 

      Gai, Xiaolei (Universität Ulm, 2018-05-16)
      This dissertation describes Phase Locked Loop (PLL) based Local Oscillator (LO) designs for RF front-end modules targeting wideband wireless communications systems from microwave to millimeter-wave ranges. With the increase ...
    • Wide-angle scanning cavity antenna element for mobile satcom applications at Ka band 

      Beitrag zu einer Konferenz
      Chaloun, Tobias; Waldschmidt, Christian; Menzel, Wolfgang (Universität Ulm, 2016)
      A novel dual linearly polarized cavity antenna with excellent scan performance up to 60◦ in both E- and H-plane is presented. The highly integrated antenna element for Ka band Satcom on the move applications is operating ...
