    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

  3. 2. A Transparent Dual-Band Cubesat Antenna Array Based on Stacked Patches

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Fernando Franzén; Harald Hultin; Jonas Olsson; [2017]
    Keywords : ;

    Abstract : This work has the scope of developing a transparentantenna for CubeSats. A CubeSat is a type of miniature satellitethat is popular due to cheaper launches and standardized dimensions.Small satellites have a limited surface area which usuallyis covered by solar panels. By making the antenna transparent,it can be mounted on top of the solar panels. READ MORE
