A comprehensive tutorial on the design and practical
applications of antenna arrays
An antenna array is an assembly of antenna elements that
maximizes a received or transmitted signal in a desired direction.
This practical book covers a wide range of antenna array topics
that are becoming increasingly important in wireless applications,
with emphasis on array design, applications, and computer
modeling.
Each chapter in Antenna Arrays builds upon the previous
chapter, progressively addressing more difficult material.
Beginning with basic electromagnetics/antennas/antenna systems
information, the book then deals with the analysis and synthesis of
arrays of point sources and their associated array factors. It
presents a sampling of different antenna elements that replace
these point sources, then presents element configurations that do
not have to lie along a line or in a plane.
The complex and difficult-to-predict interactions of elements
and electromagnetic waves are introduced, along with computer
modeling and experiments that are necessary for predicting the
performance of arrays where mutual coupling is important. Then,
various approaches to getting signals to and from the array
elements to a computer where the signal detection takes place are
explored, as are the numerical techniques behind smart
antennas.
The book emphasizes the computational methods used in the design
and analysis of array antennas. Also featured are signal processing
and numerical modeling algorithms, as well as pictures of antenna
arrays and components provided by industry and government sources,
with explanations of how they operate.
Fully course-tested, Antenna Arrays serves as a complete
text in phased array design and theory for advanced undergraduate-
and graduate-level courses in electronics and communications, as
well as a reference for practicing engineers and scientists in
wireless communications, radar, and remote sensing.
