Microwave and Radar Engineering with Lab Manual

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.
