Microwave Engineering has been used extensively since World War II when the sources
were based on vacuum tubes. Microwaves are playing a vital role in communication
engineering such as radar system, satellite communication, TV broadcasting and mobile
communication, and have wide coverage in defense, medical, domestic and industrial applications.
A through knowledge of microwave engineering and its application is very necessary for B.Tech.
students pursuing course in Electronics and Communication Engineering.
This book is intended for all students for B.Tech., sixth semester of Electronics and
Communication Engineering, studying in different colleges affiliated to Uttar Pradesh Technical
University Lucknow, Maharshi Dayanand University, Rohtak and other Indian Universities. It can
also be used as a reference tool for engineers and managers working in the various areas that
contribute to development, procurement, manufacture and applications of Microwave and Radar
Engineering.
The contents of the book is divided into nine chapters. Chapter 1 introduces the subject with
its background, advantages, and applications. Chapter 2 explains the various microwave transmission
line such as rectangular waveguide, circular waveguide, and planar transmission line. Chapter 3
deals with various microwave components like E-plane tee, H-plane tee, magic tee, directional
coupler, isolator and circulator. Chapter 4 is concentrated on explanation of various resonating
structures at microwave frequencies. Chapter 5 describes the measurement of various quantities
like wavelength, VSWR, impedance, attenuation, power, and radiation pattern at the microwave
frequencies. Chapter 6 discusses the basic microwave tubes like klystron, travelling wave tube,
magnetron, and BWO. These tubes are used in amplification and generation of microwave signals.
Chapter 7 deals with the microwave semiconductor devices like PIN diode, tunnel diode, varactor
diode, Gunn diode, IMPATT, and TRAPATT. Chapter 8 gives the basic principle, block diagram,
radar range equation, and types of radar. Chapter 9 explains the various components of radar
transmitter and receiver including radar antennas, display, and radar clutter. In addition, this book
also contains the laboratory manuals for Microwave lab, this will give clear ideas of conducting
experiments in the laboratory.
Students will find it easy, well-organized, lucid and self-explanatory. Each chapter contains a
large number of bottom box and comments, after each topic, which helps the students to understand
the basic concept. At the end of each chapter keywords, objective type questions, and previous
years UPTU/MDU exam based question has been given for self assessment.
Any suggestion for the improvement of the book would be cordially and thankfully accepted
with due regards.
