This book was released on 2013-07-01 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first truly comprehensive and most up-to-date handbook available on modern reflector antennas and feed sources for diversified space and ground applications. There has never been such an all-encompassing reflector handbook in print, and no currently available title offers coverage of such recent research developments. The Handbook consists of three volumes. Volume I provides a unique combination of theoretical underpinnings with design considerations and techniques. The need for knowledge in reflector antennas has grown steadily over the last two decades due to increased use in space and ground applications, as well as their high gain and wide bandwidth capabilities at relatively low cost. This volume brings you to the leading edge of developments in the field related to numerical techniques, classical reflector geometries, adaptive reflector antennas, shaped reflectors, bifocal and bicollimated dual reflectors, advanced reflectors, and reflect arrays. A must-have reference for both practicing engineers as well as academic researchers.

Download or read book Fields in the Focal Region of Paraboloid and Offset Paraboloid Reflectors written by R. H. Ott and published by . This book was released on 1986 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: While much development has been accomplished for reflector antenna technology, a need still exists in evaluating the impacts of design parameters. One such area lists with the design tradeoffs associated with the beam-scanning performance of reflector designs. A surface current integration analysis is derived which is exact to the order of physical optics. This analysis is applied to both circular and offset reflectors for on-axis and off-axis illumination for parameters which span the cases for which both substantial and minimal degradation with beam scan occur. The output of the analysis is cast in the form of contour plots defining the field structure in the focal region of the reflector. The results of the analyses compare favorably with data previously obtained for specialized parameters. Keywords include: Physical Optics Currents, Numerical Integration, Cassegrain Antenna, Offset Paraboloid Antenna, Contour Plots for Fields, and Angle of Scan.
Download or read book Analysis of Reflector Antennas written by W. V. T. Rusch and published by Academic Press. This book was released on 2013-10-22 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analysis of Reflector Antennas provides information pertinent to the analysis of reflector-antenna systems. This book provides an understanding of how design data have been and can be derived. Organized into four chapters, this book begins with an overview of the history of focusing reflector-antenna systems characterized by a highly variable level of general interest. This text then examines the solutions of the scalar Helmholtz equation in rectangular and spherical coordinates. Other chapters consider antenna performance described in terms of several fundamental properties, including capture area, directivity, gain, beam efficiency, aperture efficiency, polarization, effective noise temperature, and phase center. This book discusses as well the resulting functional dependence between axial ratio and component amplitude, which is the same as that between voltage standing wave ratio and voltage reflection coefficient. The final chapter deals with the role of the special-purpose digital computers. This book is a valuable resource for research and development engineers.

Download or read book Handbook of Reflector Antennas and Feed Systems Volume II Feed Systems written by Lotfollah Shafai and published by Artech House. This book was released on 2013-07-01 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first truly comprehensive and most up-to-date handbook available on modern reflector antennas and feed sources for diversified space and ground applications. There has never been such an all-encompassing reflector handbook in print, and no currently available title offers coverage of such recent research developments. The Handbook consists of three volumes. Volume II focuses on feed sources. Reflector antennas are extraordinary devices that combine high gain with geometrical simplicity, and can operate in broad frequency bands. Their performance, however, depends on the electrical characteristics of the feed system with which they operate. This comprehensive volume provides you with a solid understanding of feed system theory, design, and analysis. Featuring chapters authored by experts in each aspect of feed systems, this book takes you from fundamental mathematical techniques, electrically small and large dual reflectors, feed geometry and telemetry, tracking and command antennas, and more. Throughout the book numerous examples are provided to guide you in the practical aspects of feed design.
