    University essay from Karlstads universitet

    Author : Andreas Rogne; [2022]
    Keywords : ;

    Abstract : The fifth generation of mobile internet is upon us, but still, there is work to do before the new technology is fully utilized. The new generation of cellular network promises frequencies ranging from the sub – 6 GHz to 39 GHz, the latter being in the mmWave spectrum. READ MORE

  4. 3. Investigation of Near-Field Contribution in SBR for Installed Antenna Performance

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

    Author : Harald Hultin; [2019]
    Keywords : Shooting and Bouncing Rays; Geometrical Optics GO ; Physical Optics PO ; antenna modeling; computational electromagnetics CEM ; CST; dipole; ray tubes; Geometrisk Optik; Fysikalisk Optik; antennmodellering; elektromagnetism; CST; dipol;

    Abstract : To investigate near-eld contributions for installed antennas, an in-house code iswritten to incorporate near-eld terms in Shooting and Bouncing Rays (SBR). SBRis a method where rays are launched toward an object and scatter using GeometricalOptics (GO). These rays induce currents on the object, from which the totalscattered eld can be found. READ MORE
