Thesis (MScEng (Electrical and Electronic Engineering))--University of Stellenbosch, 2008. / An existing antenna used in satellite communications is investigated with the
goal of improving low angle radiation performance and reducing manufacturing
costs. To understand this antenna it is modelled, simulated and verified
against existing measurements. This verified model is the basis for further
investigation. The antenna is separated into two parts with are individually
examined and enhancements are proposed for each. Simulations of the resulting
final models show that little by way of improvement in the performance can
be obtained but bring several key issues to light. The scanning impedance is
of particular importance in such an investigation and a method of determining
this impedance is recommended.
