In this project, it presents three different designs of 16-element array arrangements for operation at 5.8GHz.

The study includes of the development of a threedimensional antenna model, antenna simulation and analysis of results based on various outputs of the CST Microwave Studio software package. In order to compare the performance of the antenna in larger array, a 64-element array configuration is considered. The design has been fabricated and the prototype been analyzed using the results from Network Analyzer. The performances of the antennas have been discussed and analyzed in term of return loss, bandwidth, Half- Power Beam width (HPBW), gain and directivity, and antenna efficiency. The results of the analysis suggest that the antenna with minimum number of discontinuities such as bends and T-junctions are found to give reduced levels of side lobe radiation, increased gain and directivity, and a better antenna efficiency. 2010 Thesis http://eprints.utm.my/id/eprint/26918/ masters Universiti Teknologi Malaysia, Faculty of Electrical Engineering Faculty of Electrical Engineering |
