This book was released on 1969 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: The author shows that the amplitude of a radio wave propagating at a finite angle to the surface of the earth, taking into account the earth's conductivity and the directivity of the antenna, can be calculated in terms of the components of the Hertz vector and of the electromagnetic field of a vertical antenna over an ideal earth, by introducing the concept of surface impedance and the attenuation factor. He then presents directivity patterns for a dipole placed on the surface, as functions of the parameters of the earth that are encountered in practice. An analysis of the numerical data shows that the influence of the earth's finite conductivity can cause an appreciable attenuation of a wave reflected from the ionosphere, especially in the case of poorly conducting ground.

Book Synopsis Handbook of Antennas in Wireless Communications by : Lal Chand Godara
Download or read book Handbook of Antennas in Wireless Communications written by Lal Chand Godara and published by CRC Press. This book was released on 2018-10-03 with total page 894 pages. Available in PDF, EPUB and Kindle. Book excerpt: The move toward worldwide wireless communications continues at a remarkable pace, and the antenna element of the technology is crucial to its success. With contributions from more than 30 international experts, the Handbook of Antennas in Wireless Communications brings together all of the latest research and results to provide engineering professionals and students with a one-stop reference on the theory, technologies, and applications for indoor, hand-held, mobile, and satellite systems. Beginning with an introduction to wireless communications systems, it offers an in-depth treatment of propagation prediction and fading channels. It then explores antenna technology with discussion of antenna design methods and the various antennas in current use or development for base stations, hand held devices, satellite communications, and shaping beams. The discussions then move to smart antennas and phased array technology, including details on array theory and beamforming techniques. Space diversity, direction-of-arrival estimation, source tracking, and blind source separation methods are addressed, as are the implementation of smart antennas and the results of field trials of systems using smart antennas implemented. Finally, the hot media topic of the safety of mobile phones receives due attention, including details of how the human body interacts with the electromagnetic fields of these devices. Its logical development and extensive range of diagrams, figures, and photographs make this handbook easy to follow and provide a clear understanding of design techniques and the performance of finished products. Its unique, comprehensive coverage written by top experts in their fields promises to make the Handbook of Antennas in Wireless Communications the standard reference for the field.

Book Synopsis Antenna Theory by : Constantine A. Balanis
Download or read book Antenna Theory written by Constantine A. Balanis and published by John Wiley & Sons. This book was released on 2005-04-04 with total page 1136 pages. Available in PDF, EPUB and Kindle. Book excerpt: The discipline of antenna theory has experienced vast technological changes. In response, Constantine Balanis has updated his classic text, Antenna Theory, offering the most recent look at all the necessary topics. New material includes smart antennas and fractal antennas, along with the latest applications in wireless communications. Multimedia material on an accompanying CD presents PowerPoint viewgraphs of lecture notes, interactive review questions, Java animations and applets, and MATLAB features. Like the previous editions, Antenna Theory, Third Edition meets the needs of electrical engineering and physics students at the senior undergraduate and beginning graduate levels, and those of practicing engineers as well. It is a benchmark text for mastering the latest theory in the subject, and for better understanding the technological applications. An Instructor's Manual presenting detailed solutions to all the problems in the book is available from the Wiley editorial department.
