Abstract:
Antennas have been the most neglected of all the components in personal communications systems. Yet, the manner in which energy is distributed into and collected from surrounding space has a profound influence on the efficient use of spectrum, the cost of establishing new networks, and the service quality provided by those networks.
There are two fundamental types of antennas, Omni-directional (radiates equally in all directions), and directional (radiates more in one direction than the other)
The objective of this thesis is to study the creation of radiations, some of the features and parameters of antennas, and to maintain an optimization of radiation pattern by utilizing a nonuniform antenna array of Dolph-Tschebyscheff, which is a trade-off between the beamwidth and side lobe levels.
