    Thesis: Cost Effective Antenna Design for Small Satellite Pulsed and LFMCW RaDAR

    • 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
      5. Mentored another Ph.D. student in aerodynamics with simulators’ experience and mission analysis design. 

     

    B.Eng (2nd Upper), Electrical Engineering 2005

    National University of Singapore, Singapore

    Final Year Project: Study of Human Head Effects on UWB Antenna

    • Designed a small Ultra Wide-Band (UWB) antenna with isotropic radiation pattern
    • Investigated the effect of the presence of the human head on the antenna
    • Discovered the human head does not absorb much of the Radio Frequency (RF) but acts as a ground plane in the UWB range
    • Skills acquired: 
      1. Numerical simulator XFDTD 
      2. Far field antenna measurement using anechoic chamber

    • Awarded 2 patents
    • Skills acquired:
      1. Numerical simulator IE3D
      2. HF near field measurement

    Project: Ultra High Frequency (UHF) Radio Frequency IDentification (RFID) Study
