Описание: This practical book shows the procedure to integrate, in a practical way, empirical propagation methods with geographical information systems (GIS) to obtain the radio coverage in open environments. It includes the theoretical explanation of empirical methods and GIS but as a basis to develop a real tool that combines both aspects to provide the user a suitable method for the wireless network planning in urban areas. The book introduces the empirical propagation methods and their application to wireless network planning.
The motivation for combining them with the information obtained from geographical information systems is illustrated as well as their application to real situations. The most important empirical methods used to calculate the propagation in open environments are reviewed. Focus is given to the geometrical information needed to prove the necessity of obtaining some geographical information if these methods must be applied to realistic network planning.
A review of the most important GIS is also described. The advantages and disadvantages of every system is analyzed from the point of view of its integration with an empirical propagation method. An application that combines a geographical information system with an empirical propagation method is fully described.
The practical features of this integration are completely studied to allow an engineer to use and develop his own tool. Examples are given in each chapter to fully describe and illustrate the process.

Описание: This practical text gives engineers and technicians at all levels an easy-to-follow entry point into the subject of RF/EM wave propagation and antennas. While aimed primarily at those who are entering the field or transitioning from a related field, the book also helps experienced professionals obtain a more refined understanding of the various methodologies and processes in this area.The book covers the essentials, practices, technical details, and considerations needed to help a team of engineers design, install, and/or predict the technical performance of a new (or even existing) one-way, two-antenna (long radiating distance) RF communication system. The chapters are organized logically to walk you step by step through the application processes, showing you proven methods to bring about top performance, while also helping you factor in unanticipated variances, including those caused by the earth itself, earth`s gaseous atmosphere, rain, snow, hail, ice, ionospheric signal attenuation, and EM waves. This kind of understanding and consideration saves time, money, and much frustration in a project.With this book in hand, you will better understand RF/EM wave propagation and the technical vernacular used to describe it; become familiar with the various processes and considerations in analyzing, designing, and predicting the performance of new and existing antenna RF communications systems; and more confidently approach problem solving and possible solutions for reducing signal interference and loss.The chapter contents, while not sparing the reader exposure to radiated RF system design and analysis terminology, are written in a relaxed, conversational tone and easy-to-understand manner, making this a perfect learning tool for those entering or transitioning to this field, as well as an excellent supplement or foundational text for an instructional course. The book`s logically organized and easy-to-access chapter structure also facilitates its use as a bench reference for quick lookup or review.

Описание: In recent years, transmitarray antennas have attracted growing interest with many antenna researchers. Transmitarrays combines both optical and antenna array theory, leading to a low profile design with high gain, high radiation efficiency, and versatile radiation performance for many wireless communication systems. In this book, comprehensive analysis, new methodologies, and novel designs of transmitarray antennas are presented.Detailed analysis for the design of planar space-fed array antennas is presented. The basics of aperture field distribution and the analysis of the array elements are described. The radiation performances (directivity and gain) are discussed using array theory approach, and the impacts of element phase errors are demonstrated.The performance of transmitarray design using multilayer frequency selective surfaces (M-FSS) approach is carefully studied, and the transmission phase limit which are generally independent from the selection of a specific element shape is revealed. The maximum transmission phase range is determined based on the number of layers, substrate permittivity, and the separations between layers.In order to reduce the transmitarray design complexity and cost, three different methods have been investigated. As a result, one design is performed using quad-layer cross-slot elements with no dielectric material and another using triple-layer spiral dipole elements. Both designs were fabricated and tested at X-Band for deep space communications. Furthermore, the radiation pattern characteristics were studied under different feed polarization conditions and oblique angles of incident field from the feed.New design methodologies are proposed to improve the bandwidth of transmitarray antennas through the control of the transmission phase range of the elements. These design techniques are validated through the fabrication and testing of two quad-layer transmitarray antennas at Ku-band.A single-feed quad-beam transmitarray antenna with 50 degrees elevation separation between the beams is investigated, designed, fabricated, and tested at Ku-band.In summary, various challenges in the analysis and design of transmitarray antennas are addressed in this book. New methodologies to improve the bandwidth of transmitarray antennas have been demonstrated. Several prototypes have been fabricated and tested, demonstrating the desirable features and potential new applications of transmitarray antennas.
