PREFACE

Today, the state of the art antenna technology allows the use of different
types and models of antennas, depending on the area of application
considered. The rapid progress in wireless communications requires the
development of lightweight, low profile, small size, flush-mounted and
wideband multi-frequency planar antennas. This book reviews recent advances
in designs of various microstrip patch antenna configurations.
Microstrip patch antennas have been widely used in the range of
microwave frequencies over the past twenty five years, and over the past few
years, single-patch antennas are extensively used in various communication
systems due to their compactness, economical efficiency, light weight,
low profile and conformability to any structure. The main drawback to
implementing these antennas in many applications is their limited bandwidth.
However, the most important challenge in microstrip antenna design is to
increase the bandwidth and gain. Theoretical study of various patch antenna
configurations will be carried out in this book. The study is performed by
using full wave analysis and analytical techniques for the characterization of
these structures. Several techniques will be used in this book to achieve multi-
band performances such as multilayer stacked patches, multiple patches and
insertion of slots of different shapes and sizes in the patch antennas. In
addition, some novel patch antenna designs for modern applications will be
given, and some challenges of patch antenna designs will also be addressed.
This book presents new research in this dynamic field and will be divided
into seven chapters.
Chapter 1 begins with a brief discussion of microstrip patch antenna and
the different methods of analysis used to treat this kind of antenna, the chapter
then discusses the different substrate materials used for this type of antenna

and the influence of the appearance of the surface waves on the radiation
characteristics and the choices to make in order to limit their excitation. Also
the chapter discusses in general terms the dependence of the antenna
characteristics according to their physical parameters and the different feeding
methods encountered in the literature. Chapters 2 and 3 present an accurate
design of both rectangular and circular patch antennas by using an analytical
technique and an integral equation method, where some mathematics and
electromagnetic backgrounds are discussed. In chapter 4, the current of
rectangular and circular patches is calculated by the application of a various
basic functions, the study of a novel asymptotic forms allow to a simplified
algebraic formulation and a much reduced computing time. Chapter 5
describes the moments method analysis of a rectangular microstrip patch
antenna with non zero surface impedance which printed on isotropic or
uniaxial anisotropic substrate, in this new model of calculation, the necessary
terms of representing the surface resistance on the patch are derived and are
included in the equation in the form of a resistance matrix. Once the
impedance matrix and the resistance matrix are calculated, the results form a
system of simultaneous equations, the resulting system of equations is then
solved for the unknown current modes on the patch. Chapter 6 reviews a
resistive rectangular microstrip antenna fed by a microstripline and printed on
the anisotropic substrate with a superstrate. Chapter 7 is concerned with
broadbanding techniques, where the analysis of rectangular and circular
patches loaded with different shaped slots are discussed. Moreover, bilayer
biconductor microstrip patch antenna with various slots are also presented.

Chapter 1: General principles of microstrip patch antennas;
Chapter 2: Analysis of patch antenna by analytical techniques;

basis functions;
