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.

Download or read book Amateur Radio HF Antennas written by Claude Jollet and published by Claude Jollet. This book was released on with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The contents of this book are mostly aimed at the amateur radio beginner and aspiring ones. Therefore, this book provides answers to basic questions like: What is the best HF antenna for my needs and location? What type of stand-alone antenna tuner should I use and which should I avoid? How can I hide my HF antenna from the neighbors and still get acceptable performance from it? What about lightning protection? This book will supply immediately useful answers to the above questions and many more. A properly designed and installed amateur radio HF antenna system can potentially make the humblest ham radio equipment perform like stations worth thousands of dollars. We are confident that the antenna experimenter will find the information given here priceless. Furthermore, any ham radio operator, armed with the information this book contains, will become a much better informed buyer of commercially made HF antenna systems and accessories. This special compendium edition is published in response to ham radio operators who wrote to ask that all the basic information, on and related to amateur radio HF antennas, be made available in one book instead of four, arguing that it would be more convenient. The author and publisher agree. Therefore this edition contains the complete four-book series on Amateur Radio HF Antennas published by Claude Jollet, VE2DPE.

Download or read book Hogwash for Hamsters written by Jerry Spring and published by Trafford Publishing. This book was released on 2008-11-19 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: The author investigates the humor behind amateur radio, a hobby that has captivated numerous people throughout the world for almost a century. Contrary to popular belief, the hobby continues to grow as it develops and incorporates new technologies, including digital communications, computers, internet, satellites, and so on. While some are into building their own equipment, others are more focused on chasing faint signals in distant lands or competing for bragging rights in various contests. Most would gladly consider themselves as nerds for it takes a lot of dedication and knowledge to obtain a license and successfully operate a radio station. Among all the technical mumbo-jumbo, however, there is a lighter side, which is brought out in Hogwash for Hamsters. When we take ourselves less seriously, we become even better ambassadors to the world. So enjoy the limericks, songs, riddles, one liners, and stories. It might just make your day a little brighter.
Download or read book Automotive Antenna Design and Applications written by Victor Rabinovich and published by CRC Press. This book was released on 2017-12-19 with total page 366 pages. Available in PDF, EPUB and Kindle. 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.
