Book Synopsis Basic Principles of Fresnel Antenna Arrays by : Igor V. Minin
Download or read book Basic Principles of Fresnel Antenna Arrays written by Igor V. Minin and published by Springer Science & Business Media. This book was released on 2008-05-31 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Antennas represent a critical technology in any of these wireless systems. Not only do they directly affect the received power of the system, they are also typically the largest and most visible part. Recently, the need for low-cost, low-profile, and lightweight antenna in the frequency range of the microwave/millimeter wave/THz band has regained momentum. "Basic Principles of Fresnel Antenna Arrays" provides us a with the basics of the various Fresnel Antenna approaches, in order to achieve low-cost, low-profile, and lightweight antenna in the microwave/millimeter wave band. A potential solution of the antenna problem lies in using lens technology in an array. The Fresnel zone plate lens (FZPL) antenna is in particular an interesting candidate for the array element. The limiting focusing properties of FZPL including subwave length focus are described in detail. The book further presents a novel hexagonal FZPL antenna which can be more effectively packed in an array due to its shape. Before considering the hexagonal FZPL antenna in an array, the authors investigate two ideas, described as methods to potentially improve the radiation characteristics. The first idea is to change the reference phase of the Fresnel zone radii - a novel free parameter in the usual design of zone plate’s lenses and antennas. To further improve the radiation characteristics of the hexagonal FZPL antenna, a technique involving Fresnel zone rotation is investigated. The book is of interest for designers of optical systems because, taking scaling effects into account, the characteristics of diffractive quasioptical elements are valid for diffractive focusing elements of integrated optics.
Book Synopsis Fresnel Zones for Ground-Based Antennas by : J. Bach Andersen
Download or read book Fresnel Zones for Ground-Based Antennas written by J. Bach Andersen and published by . This book was released on 1963 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ordinary Fresnel zone concept is extended to include the influence of finite con ductivity. This is important for ground-based antennas because the influence on the radiation pattern of irregularities near the antenna is determined by the amplitude and phase of the groundwave. Only discontinuities of the elec trical parameters of the ground are considered. Extensive numerical results for the first Fresnel zone are given, and it is shown that the zone is much smaller for a finite conductivity than for an infinite conductivity, especially for small angles of elevation.

Book Synopsis New Variable for Fresnel Zone Plate Antennas by : G. W. Webb
Download or read book New Variable for Fresnel Zone Plate Antennas written by G. W. Webb and published by . This book was released on 2003 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: I present experimental results and analysis on the application of a new variable in the design of zone plate antennas. This variable is the choice of phase reference used in the definition of the Fresnel zones from which zone plates arc constructed. The standard zone plate construction assumes a specific choice for this reference phase which, however, can be chosen to have any value between 0 degrees and 360 degrees. When the reference phase is varied, antenna pattern measurements reveal small systematic changes in the main lobe gain accompanied by large improvements in the overall sidelobe level and position in both the E- and H-planes. Measurements also show that through variation of the reference phase, the phase of the main lobe can be varied controllably through 3600. I conclude that reference phase is a useful new tool available to the zone plate antenna designer.
Book Synopsis Introduction to Antennas and RF Propagation Analysis by : Dean James Friesen
Download or read book Introduction to Antennas and RF Propagation Analysis written by Dean James Friesen and published by Artech House. This book was released on 2021-12-31 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
