Antenna and Wave Propagation is a textbook written by Bakshi that covers the fundamentals of electromagnetic radiation, antenna theory, and wave propagation in various media. The book is intended for undergraduate and postgraduate students of electronics and communication engineering, as well as for professionals and researchers in the field of wireless communication.
The book consists of 12 chapters that are organized into three parts. The first part deals with the basics of electromagnetic waves, such as Maxwell's equations, polarization, reflection, refraction, and transmission. The second part focuses on antenna theory, such as radiation mechanism, antenna parameters, antenna arrays, aperture antennas, and special antennas. The third part covers wave propagation in different media, such as free space, ionosphere, troposphere, and earth.
The book is written in a clear and concise manner, with numerous examples, diagrams, and tables to illustrate the concepts. The book also provides solved problems and exercises at the end of each chapter to test the understanding of the readers. The book is based on the revised syllabus of Rajasthan Technical University (RTU) and other Indian universities.[^1^]
Antenna and Wave Propagation by Bakshi is a comprehensive and useful text for students and practitioners of wireless communication. It covers the essential topics in a systematic and logical way, with an emphasis on physical insight and practical applications. The book is available as an ebook in PDF format.[^2^]
Antennas and wave propagation are important topics for various applications in wireless communication, such as radio, television, radar, satellite, cellular, and wireless networks. Antennas are devices that convert electrical signals into electromagnetic waves and vice versa. Wave propagation is the study of how electromagnetic waves travel through different media, such as free space, air, water, and earth.
There are different types of antennas, such as wire antennas, loop antennas, horn antennas, parabolic antennas, microstrip antennas, and array antennas. Each type of antenna has its own advantages and disadvantages, depending on the frequency, bandwidth, polarization, directivity, gain, and efficiency. Antenna design is a challenging task that requires a good understanding of electromagnetic theory and optimization techniques.
Wave propagation can be classified into three categories: ground wave propagation, sky wave propagation, and space wave propagation. Ground wave propagation occurs when electromagnetic waves follow the curvature of the earth's surface. Sky wave propagation occurs when electromagnetic waves are reflected by the ionosphere. Space wave propagation occurs when electromagnetic waves travel in a straight line through free space. Wave propagation is affected by various factors, such as atmospheric conditions, terrain features, and obstacles.
Antennas and wave propagation have many applications in different fields of engineering and science. Some examples are: air traffic control[^1^], surface ship radar[^1^], maritime vessel traffic control[^2^], defense tracking[^2^], vehicle speed detection[^2^], radio broadcasting[^3^], television broadcasting[^3^], satellite communication[^3^], cellular communication[^3^], wireless networks[^3^], remote sensing[^3^], radio astronomy[^3^], and biomedical imaging[^3^]. Antennas and wave propagation are also relevant for emerging technologies, such as 5G communication[^1^], Internet of Things (IoT)[^1^], smart cities[^1^], and wireless power transfer[^1^]. aa16f39245
