This book provides readers with a solid understanding of the
concepts involved in the propagation of electromagnetic waves and
of the commonly used modeling techniques. While many books cover RF
propagation, most are geared to cellular telephone systems and,
therefore, are limited in scope. This title is comprehensive-it
treats the growing number of wireless applications that range well
beyond the mobile telecommunications industry, including radar and
satellite communications.
The author's straightforward, clear style makes it easy for readers
to gain the necessary background in electromagnetics, communication
theory, and probability, so they can advance to propagation models
for near-earth, indoor, and earth-space propagation. Critical
topics that readers would otherwise have to search a number of
resources to find are included:
* RF safety chapter provides a concise presentation of FCC
recommendations, including application examples, and prepares
readers to work with real-world propagating systems
* Antenna chapter provides an introduction to a wide variety of
antennas and techniques for antenna analysis, including a detailed
treatment of antenna polarization and axial ratio; the chapter
contains a set of curves that permit readers to estimate
polarization loss due to axial ratio mismatch between transmitting
and receiving antennas without performing detailed
calculations
* Atmospheric effects chapter provides curves of typical
atmospheric loss, so that expected loss can be determined
easily
* Rain attenuation chapter features a summary of how to apply the
ITU and Crane rain models
* Satellite communication chapter provides the details of
earth-space propagation analysis including rain attenuation,
atmospheric absorption, path length determination and noise
temperature determination
Examples of widely used models provide all the details and
information needed to allow readers to apply the models with
confidence. References, provided throughout the book, enable
readers to explore particular topics in greater depth.
Additionally, an accompanying Wiley ftp site provides supporting
MathCad files for select figures in the book.
With its emphasis on fundamentals, detailed examples, and
comprehensive coverage of models and applications, this is an
excellent text for upper-level undergraduate or graduate students,
or for the practicing engineer who needs to develop an
understanding of propagation phenomena.
