My main research area is antenna arrays, with specific contribution in
* slotted waveguide arrays, including single resonant slot analysis, leaky-wave slot analysis, slot array design and analysis, and design and analysis of waveguide feed components for slotted waveguide arrays,
* array synthesis techniques,
* patch radiators and arrays, CPW slot arrays.
A secondary research area where I have made some contributions is in electromagnetic antenna and scattering measurements, using the Compact Antenna Range facility of the University of Pretoria as vehicle for the research.
