Volume II covers antenna theory and design, describing a number of antenna types, including receiving, wire and loop, horn, frequency-independent, microstrip, refelector, and lens antennas. This section also includes arrays, providing array theory as well as exploring waveguide-fed slot arrays, peiodic arrays, and aperiodic arrays.




Numerical Approach for Predicting Radiation Patterns of HF-VHF Antennas Over Irregular Terrain


Book Description

The feasibility of using physical optics approximation for computing radiation patterns of ground-based HF-VHF antennas in the presence of known ground irregularities is investigated. A computer program was written for physical optics formulation to evaluate the composite radiation patterns of a line source above an irregular, but deterministic, perfectly conducting surface. For the special case of a line source above a perfectly conducting plane with semicylindrical boss,the exact field expressions are derived, and the numerical results are compared with those obtained by physical optics for the same geometry. An error criterion that gives a meaningful error estimate at both the maxima and minima values of the radiation pattern is formulated and applied to the computed result. It is concluded that physical optics approximations can be used for predicting the radiation patterns of ground-based HF-VHF antennas.

Handbook of Antennas in Wireless Communications


Book Description

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.
