About this eBook

Preface This book is the result of long discussions among the fifth semester students of Electronics and Communication Engineering at DAV Institute of Engineering and Technology. The objective of the course Antenna and Wave Propagation is to provide an introduction to the fundamental principles of antennas and wave propagation for communication engineers. This book may also be used by practicing engineers in the field of antenna design and for general science reader who wants to refresh his her knowledge in the subject. This book differs from currently existing books on the same subject as there is more emphasis on mathematical explanation in addition to physical understanding. To grasp the subject properly the reader should have sound understanding of electromagnetic field theory, college level physics, integral and vector calculus. In the book physical principles are explained with sufficient detail with very good diagrams that other books lack. This book may also be useful for senior physics graduates. The first chapter is a brief introduction to electromagnetic waves which the students have already studied in earlier semesters. The second chapter develops the physical understanding of radiation mechanism. The third chapter gives the parameters associated with antenna namely directivity, gain, radiation pattern etc. All these parameters are necessary to design and to measure the performance of antenna. The third, fourth and the fifth chapters describe the various types of antennas including hertzian dipole, linear antenna, antenna arrays, and the aperture antennas. Sufficient mathematical analysis is also provided. The last two chapters give the physical mechanism of various types of propagation processes. I express my sincere thanks to those reviewers and others whose suggestions have been contributed in this text book. In particular I thank Sh. C L Kochher Director-cum-Principal, DAVIET for motivational support. I also thank Prof. Kuldeep Sharma for helping me in mathematical analysis. Kamal Kishore
