Download or read book Antenna Arrays written by Randy L. Haupt and published by John Wiley & Sons. This book was released on 2010-09-09 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive tutorial on the design and practical applications of antenna arrays An antenna array is an assembly of antenna elements that maximizes a received or transmitted signal in a desired direction. This practical book covers a wide range of antenna array topics that are becoming increasingly important in wireless applications, with emphasis on array design, applications, and computer modeling. Each chapter in Antenna Arrays builds upon the previous chapter, progressively addressing more difficult material. Beginning with basic electromagnetics/antennas/antenna systems information, the book then deals with the analysis and synthesis of arrays of point sources and their associated array factors. It presents a sampling of different antenna elements that replace these point sources, then presents element configurations that do not have to lie along a line or in a plane. The complex and difficult-to-predict interactions of elements and electromagnetic waves are introduced, along with computer modeling and experiments that are necessary for predicting the performance of arrays where mutual coupling is important. Then, various approaches to getting signals to and from the array elements to a computer where the signal detection takes place are explored, as are the numerical techniques behind smart antennas. The book emphasizes the computational methods used in the design and analysis of array antennas. Also featured are signal processing and numerical modeling algorithms, as well as pictures of antenna arrays and components provided by industry and government sources, with explanations of how they operate. Fully course-tested, Antenna Arrays serves as a complete text in phased array design and theory for advanced undergraduate- and graduate-level courses in electronics and communications, as well as a reference for practicing engineers and scientists in wireless communications, radar, and remote sensing.

Book Synopsis Wideband Parallel-Plate Waveguide, Phased-Array Antenna by :
Download or read book Wideband Parallel-Plate Waveguide, Phased-Array Antenna written by and published by . This book was released on 1987 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: A need exists for wideband phased array radars. This report presents the results of some experimental studies made on improving bandwidth and scanning range performance of phased array antennas. A parallel plate waveguide element, operating in the S band (2.8 to 4.2 GHz) was used as the radiating element. SUch an element permitted the needed less than one-half wavelength interelement spacing for broadband applications and has been found to provide good aperture matching for H plane scanning. The element is fed by a broadband, end on, base fed, coaxial to waveguide transition. H plane waveguide simulators have been used to study aperture match performance and to optimize array parameters to improve bandwidth and scan range. The waveguide simulator results showed that a good aperture match, with voltage standing wave ratio (VSWR) of about 2.1 over a 40% bandwidth and + or - 60 deg scan angle, is achievable for H-plane scanning. Experimentally optimized array parameters are then used to build an 11 x 11 element array. The scanning performance of that array in H and E planes was studied by measuring active element patterns. This does not give precise results, but did show that the aperture match is about equally good, over + or - 60 and 40% bandwidth, for H and E plane scanning. Keywords: Phased arrays; Wide bandwidth; Experimental studies; Aperture matching; Parallel plate waveguides; Waveguides simulators; Active element pattern.
Book Synopsis Processing for Maximum Signal-to-clutter in AMTI Radars by : William Bernard Goggins
Download or read book Processing for Maximum Signal-to-clutter in AMTI Radars written by William Bernard Goggins and published by . This book was released on 1974 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phased array antennas and doppler signal processors designed to complement each other have been successfully used to maximize the signal-to-clutter (S/C) performance of AMTI radars. The optimum receiving antennas described in this paper allow for nonuniformities created in the ground-clutter doppler spectrum by the transmitting antenna and processing of the received doppler signal; the optimum signal-to-clutter digital processors allow for clutter spectra shaped by the combined effects of the transmitting-receiving antennas. The emphasis has been placed on producing antenna-processor designs that have complementary pass and reject bands. The mathematical techniques used in these designs maximize the ratio between the target signal and the clutter-plus-noise, expressed as a ratio of quadratic forms. The solution for the optimum design, which depends principally on the inversion of a single matrix rather than on any recursive technique, is obtained in closed form.

Book Synopsis Array Pattern Optimization by : Jafar Ramadhan Mohammed
Download or read book Array Pattern Optimization written by Jafar Ramadhan Mohammed and published by BoD – Books on Demand. This book was released on 2019-03-27 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: Array pattern optimization is a very important and necessary issue in the majority of modern communication systems in a variety of applications such as sonar, radar, navigation, wireless communications, and many other engineering fields. Classical methods for array pattern synthesis have worked mainly with analytical models that are linear, local and, thus, their performances were not optimum. They have always been designed with closed-form mathematical models. Unlike these analytical methods, the global optimization methods with powerful computing tools offer optimum solutions. During the last few years, the design of the antenna arrays has been a topic of significant research activity. This book presents recent advances in the field of array pattern optimization. It is targeted primarily toward students and researchers who want to be exposed to a wide variety of antenna array design and optimization. It includes five chapters as well as the introductory chapter. These five chapters are categorized into five different areas depending on the application. These applications are ordered to address interference suppression, electronic toll collection, mmWave and ultra-wideband, integrated antennas, and educational packages for modeling smart antenna for 5G wireless communications. The book has the advantage of providing a collection of applications that are entirely independent and self-contained; thus, the interested reader can choose any chapter and skip to another without losing continuity.
