Research Summary

1. Proposed a novel method to achieve effective multi-directional optimization of UWB systems
2. Devised a fast and effective Smith chart based tuning algorithm to design integrated UWB slot antennas
3. Efficiently solved the problem of UWB antenna radiation characterization by developing  new theoretical concepts
4. Introduced a useful new figure of merit for Ultra-wideband (UWB) antenna performance assessment and optimization
5. Introduced an analytical model for notch-filter design for frequency notched UWB antennas to improve accuracy and reduce design times.
6. Designed, fabricated and tested two novel, low cost and low profile printed wireless antenna designs with ultra-wide bandwidths.
7. Conducted experiments at the Microwave Laboratory using vector network analyzers and measured small antennas using a modern near-field antenna measurement range by NSI systems
8. Published two IEEE transaction papers and one Electronic Letters paper based on the PhD project work
9. Published 9 papers in peer reviewed international conferences.

Computing

1. Extensive experience in simulating small antennas using HFSS by AnsoftTM
2. Used CSTTM microwave studio for time domain solving of UWB antennas and developed a systematic method to obtain radiated pulses of antennas
3. Used XFDTD from RemcomTM for modelling UWB frequency notched planar printed antennas
4. Carried out a parametric study of  planar wide-slot antennas using IE3D from ZelandTM
5. Developed efficient codes in VB Macro Language of CST, MATLAB and FORTRAN for Electromagnetic analysis.
