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 excerpt: The steady evolution of wireless communication technologies continues to pave the way for the implementation of innovative services and devices in modern vehicles. These include analog and digital audio broadcasting radio, satellite radio, GPS, cell phones, and short range communication devices. Such applications require the use multiple antennas operating in different frequency ranges. Automotive Antenna Design and Applications thoroughly examines traditional and new advanced automotive antennas, including the principles, designs, and techniques used to reduce antenna dimensions without significant degradation of communication quality. The contents of this book are based on cutting-edge data collected from numerous technical papers, patents, and patent applications. It presents an overview of many commercially available automotive antennas and covers features that have become standard in automotive applications, such as printed-on car glass antennas, reduced-size helical antennas, multiband compact, printed-on dielectric and patch designs in a single package. Includes simulation examples of antenna parameters that significantly speed up the design process using software packages such as FEKO, NEC, IE3D, and Genesys Highlighting the practical aspects of antenna design, the authors present passive and active designs and describe the entire design process, including antenna simulation, prototype sample fabrication, and laboratory test measurements. The book also covers the production adjustments that can result from the demands of the real car environment. The presentation of numerous examples of passive and active automotive antennas greatly enhances this reference’s value to professionals, students, and anyone else working in the ever-evolving field of antenna design and application.

Book excerpt: This book systematically describes advanced metric wave radar and its practical applications, offering a comprehensive introduction to the engineering design methods from the perspectives of system design, antenna/feed and transmit/receive subsystems, as well as mechanical structure design. Focusing on the height-finding method, it describes in detail how the super-resolution technique can be used to solve the problem of low-angle height finding in metric wave radar. It also discusses the anti-jamming method for the unique jamming environment. Further, it presents narrowband target recognition methods to overcome the limitations of narrow absolute bandwidth in metric wave radar and to further explore the technique’s potential. Cooperative detection for metric wave radar netting is also addressed, and the main experimental results are included. The book offers a valuable resource for professional engineers, researchers and teachers, as well as graduate students engaged in radar system engineering, electronic engineering, and signal processing.
Download or read book Plasma based Radar Cross Section Reduction written by Hema Singh and published by Springer. This book was released on 2015-09-30 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a comprehensive review of plasma-based stealth, covering the basics, methods, parametric analysis, and challenges towards the realization of the idea. The concealment of aircraft from radar sources, or stealth, is achieved through shaping, radar absorbing coatings, engineered materials, or plasma, etc. Plasma-based stealth is a radar cross section (RCS) reduction technique associated with the reflection and absorption of incident electromagnetic (EM) waves by the plasma layer surrounding the structure. A plasma cloud covering the aircraft may give rise to other signatures such as thermal, acoustic, infrared, or visual. Thus it is a matter of concern that the RCS reduction by plasma enhances its detectability due to other signatures. This needs a careful approach towards the plasma generation and its EM wave interaction. The book starts with the basics of EM wave interactions with plasma, briefly discuss the methods used to analyze the propagation characteristics of plasma, and its generation. It presents the parametric analysis of propagation behaviour of plasma, and the challenges in the implementation of plasma-based stealth technology. This review serves as a starting point for the graduate and research students, scientists and engineers working in the area of low-observables and stealth technology.

Download or read book World s Best Hobby written by Dave Bell W6AQ and published by AuthorHouse. This book was released on 2014-06-02 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: Worlds Best Hobby is an unusual title for a memoir, which is exactly what this book is. Its my life in the fascinating hobby of Amateur Radio. Much of my professional life is spent producing documentary and reality programs for television (including more than a few about Ham Radio) where I learned that the purpose of a title is to attract an audience and if it was also true, all the better. The challenge with documentary films is to make them entertaining first and foremost, and informational if possible. Ive tried very hard to make this book entertaining, and from feedback Ive gotten (from Hams and wannabee Hams who found it posted online as I was writing it) Ive succeeded, at least to some extent. I tried to make the book fun because Ham Radio is fun. And Ham Radio has more facets than a cheap diamond, as youll discover as you dig into Worlds Best Hobby. Enjoy! PS. Let me know what you think of Worlds Best Hobby especially if you like it. 73, Dave Bell, W6AQ
