Education
Ph.D., Electronics Engineering 2013
University of Surrey, United Kingdom
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:
-
- Mission analysis to see how the objective and sub-systems affect each other and the antenna design
- Wrote mode matching simulator in C programming language
- Numerical simulator HFSS
- Antenna design using analytical model and verification through numerical simulators
- 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:
-
- Numerical simulator XFDTD
- Far field antenna measurement using anechoic chamber
Victoria Junior College 2000
5 GCE “A” and 2 “AO” Level Passes
Zhonghua Secondary School 1998
8 GCE “O” Level Passes
Experience
R&D Engineer, Institute for Infocomm Research, Singapore 2005-2007
Industry Project: HF RFID Smart Shelf Proof of Concept
- Produced a proof of concept antenna to detect items on a metal shelf using only 1 planar antenna instead of the conventional solution of 2 antennas
- Awarded 2 patents
- Skills acquired:
-
- Numerical simulator IE3D
- HF near field measurement
Project: Ultra High Frequency (UHF) Radio Frequency IDentification (RFID) Study
- Studied the effectiveness of UHF RFID in the near and far field with different materials in an enclosed cluttered space
Industrial Attachment Student, DSO Laboratories 2004
Project: Satellite and Wide band Line of Sight Communication System
- Selected a propagation model and integrated into a simulator using C++ programming language
- Skills acquired:
-
- C++ programming language
