Wave propagation, including ground wave and ionospheric propagation, goes on to make this text a useful and self-contained reference on antennas and radio wave propagation. While a rigorous analysis of an antenna is highly mathematical, often a simplified analysis is sufficient for understanding the basic principles of operation of an antenna.

Synopsis: The book is written for the first course on antennas and wave propagation. The book begins with an introduction that discusses the fundamental concepts, notations, representation and principles that govern the field of antennas. A separate chapter on mathematical preliminaries is discussed followed by chapters on every aspect of antennas from maxwells equations to antenna array analysis, antenna array synthesis, antenna measurements and wave propagation. About the Author: Dr G. Raju is Professor, Department of Electronics and Communication Engineering, College of Engineering, Andhra University, Visakhapatnam, India.

Antenna and Wave Propagation textbook by Bakshi pdf free download. In wireless communication systems, signals are radiated in space as an electromagnetic wave by using a receiving transmitting antenna and a fraction of this radiated power is intercepted by using a receiving antenna. Thus, an antenna is a device used for radiating or receiver radio waves. An antenna can also be thought of as a transitional structure between free space and a guiding device (such as transmission line or waveguide).

Usually antennas are metallic structures, but dielectric antennas are also used now a day., In our discussion we shall consider only metallic antennas. Here we shall restrict our discussion to some very commonly used antenna structures. Some of the most commonly used antenna structures are shown. Time-varying currents radiate electromagnetic waves. A time varying current generates time-varying electric and magnetic fields. When such fields exist, power is generated and propagated.

Although theoretically any structure carrying time varying current can radiate electromagnetic waves, all structures are not equally efficient in doing that. While in many applications we try to reduce the radiation, when radiation is intended, the launching of waves into space is accomplished with the aid of specially designed structures called antennas.

Pratigya serial of star plus. If the time varying current density established on an antenna structure is unknown, the radiated fields can be calculated without great difficulty. A more difficult problem is determination of current density J on an antenna such that the resultant field will satisfy the required boundary conditions on the antenna surface.
