Abstract
Microstrip antennas have several advantages compared coventional microwave antennas. Some of these advantages are: low volume, light weight, low profile planar
configurations which can be made conformal.... etc.. The simplest microstrip patch configuration is undoubtly the
rectangular microstrip antenna. The simplicity of the
structure stimulated a large number of research papers, and
numerous attempts had been made to predict and evaluate the radiation characteristics of rectangular patch antenna. This thesis presents the solution of the boundary value problem associated with the microstrip structure using the full wave analysis in the spectral domain. The problem is formulated in terms of a rigorous hybrid-mode representation using the potential approach. The resulting equations are subsequently transformed via the application of Galerkin’s method in the spectral domain . This method has an attractive feature, that it gives a complete representation of the field components inside and outside the structure. It is easy to deal with the linear algebric equations instead of convlutional integeral in the space domain that takes more time . The thesis contains four chapters, the first chapter is an introductory chapter presenting a historical background, defining the microstrip antenna, discussing methods for diminishing the disadvantages and determining
