    • Investigated antenna cost factors for both pulsed and Linear Frequency Modulated Continuous Wave (LFMCW) satellite RaDAR to monitor tropical deforestation 
    • Used mutual coupling to decrease the multimode horn element’s height and effective volume in the phased array
    • Skills acquired:
      1. Mission analysis to see how the objective and sub-systems affect each other and the antenna design
      2. Wrote mode matching simulator in C programming language
      3. Numerical simulator HFSS
      4. Antenna design using analytical model and verification through numerical simulators
