Available in PDF, EPUB and Kindle. Book excerpt: The need to develop technology and communication necessitates the design of flexible and high-capacity radiating systems in today's communication infrastructure. In this context, antenna arrays are the ideal solution and have been one of the priority research subjects of the science community dealing with electromagnetics from past to present. Optimization of an array may be performed in various ways such as the optimization of excitation, reflector structure, feed network, etc. depending on the array structure. This book is a collection of seven research studies focused on the optimization of array structures in classical phased array or time modulation, including radiator, reflector, feed network, and radiating element optimizations.
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.

Book excerpt: ABSTRACTThe radiation pattern of an antenna array depends strongly on the weighting methodand the geometry of the array. Selection of the weights has received extensive attention,primarily because the radiation pattern is a linear function of the weights. However, thearray geometry has received relatively little attention even though it also stronglyinfluences the radiation pattern. The reason for this is primarily due to the complex wayin which the geometry affects the radiation pattern. The main goal of this dissertation isto determine methods of optimizing array geometries in antenna arrays.An adaptive array with the goal of suppressing interference is investigated. It isshown that the interference rejection capabilities of the antenna array depend upon itsgeometry. The concept of an interference environment is introduced, which enablesoptimization of an adaptive array based on the expected directions and power of theinterference. This enables the optimization to perform superior on average, instead of forspecific situations. An optimization problem is derived whose solution yields an optimalarray for suppressing interference. Optimal planar arrays are presented for varyingnumber of elements. It is shown that, on average, the optimal arrays increase the signalto-interference-plus-noise ratio (SINR) when compared to standard arrays.Sidelobe level is an important metric used in antenna arrays, and depends on theweights and positions in the array. A method of determining optimal sidelobeminimizing weights is derived that holds for any linear array geometry, beamwidth,antenna type and scan angle. The positions are then optimized simultaneously with theoptimal weights to determine the minimum possible sidelobe level in linear arrays. Results are presented for arrays of varying size, with different antenna elements, and fordistinct beamwidths and scan angles.Minimizing sidelobes is then considered for 2D arrays. A method of determiningoptimal weights in symmetric 2D arrays is derived for narrowband and wideband cases.The positions are again simultaneously optimized with the weights to determine optimalarrays, weights and sidelobe levels. This is done for arrays with varying number ofelements, beamwidths, bandwidths, and different antenna elements.

This book was released on 2012-12-06 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 32 (thesis year 1987) a total of 12,483 theses titles from 22 Canadian and 176 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 32 reports theses submitted in 1987, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.
