Faculty of Engineering. Dept. of Electrical and Electronic Engineering. Dissertations -- Electrical and electronic engineering Theses -- Electrical and electronic engineering Antennas (Electronics) Artificial satellitesRadio antennas 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. 2008-08-12T08:29:02Z 2010-06-01T08:41:22Z 2008-08-12T08:29:02Z 2010-06-01T08:41:22Z 2008-03 Thesis http://hdl.handle.net/10019.1/2142 en University of Stellenbosch application/pdf Stellenbosch : University of Stellenbosch |
