Download or read book Investigation of the Element Pattern in Cylindrical Phased Arrays of Circular Waveguides written by Quirino Balzano and published by . This book was released on 1972 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: The radiation from the elements in a cylindrical phased array is analyzed theoretically and experimentally. The theoretical investigation has developed a multimodal analysis method for cylindrical arrays. The method is similar to that for plane arrays, whereby, the field inside the element is represented as the superposition of a set of waveguide modes. The method allows the definition and the precise evaluation of the driving point admittance of the elements. A comparison between the driving point admittance in planar and cylindrical arrays is made and the conditions for the use of Wheeler simulators for cylindrical array element design are set. (Author).

Download or read book Phased Array Antennas with Optimized Element Patterns written by Sergei P. Skobelev and published by Artech House. This book was released on 2011 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: This authoritative resource provides you with a detailed description of ideal array element characteristics that help you estimate the quality of development of real-world phased array antennas. You find several approaches to optimum phased array design, allowing you to provide specified array gain in a specific region of scan, using a minimum number of expensive, controlled devices. Moreover, this practical book presents important numerical methods that you can use to model and optimize phased array structure to obtain the best array characteristics that the chosen structure can provide.From arrays with beam-forming networks, arrays of coupled dual-mode waveguides, and arrays with reactively loaded radiators, to waveguide arrays with protruding dielectric elements, and arrays with strip, disk, and wire structures, this comprehensive reference explains a wide range of essential topics to help you with work in this challenging area. The book is supported with over 165 illustrations and more than 566 equations.

Book excerpt: The subject material may be classified in three separate topics. These are: the analysis of dielectric slab-covered waveguide arrays on large cylinders (extended array coverage), scattering from dielectric-covered periodic screens of small rectangular apertures (broadband antenna/radome technology), and the analysis of a stripline fed notch antenna and antenna array (broadband antennas). The report briefly summarizes the first two study areas where detailed accounts are included in Scientific Report No. 1 (AFCRL-73-0587) and Scientific Report No. 2 (AFCRL-74-0173). The investigation of the notch antenna and notch antenna arrays for broadband application are the primary subject material covered in the report.

Download or read book Analysis of Circular Waveguide Arrays on Cylinders written by Hans Steyskal and published by . This book was released on 1974 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flushmounted array antennas that conform to cylindrical surfaces are of particular interest for airborne applications since the shape of the aircraft or missile often is well approximated by such a surface. The report gives a mathematical model for a finite array antenna with circular waveguide elements on a cylinder. The approach allows arbitrary element spacings and applies to cylinders with radii > 2 wavelengths, thus it also includes planar arrays. The array is described by a scattering matrix and from the scattering coefficients all other array parameters are derived. For pracrical cases of interest, the curvature is small in terms of wavelengths and therefore appropriate asymptotic expansions for the magnetic field Green's function are derived for the two basic cases of an axial and circumferential magnetic current element on the cylinder. Illustrative numerical examples are included.

Available in PDF, EPUB and Kindle. Book excerpt: An in-depth treatment of array phenomena and all aspects of phased array analysis and design Phased Array Antennas, Second Edition is a comprehensive reference on the vastly evolving field of array antennas. The Second Edition continues to provide an in-depth evaluation of array phenomena with a new emphasis on developments that have occurred in the field over the past decade. The book offers the same detailed coverage of all practical and theoretical aspects of phased arrays as the first edition, but it now includes: New chapters on array-fed reflector antennas; connected arrays; and reflect arrays and retrodirective arrays Brand-new coverage of artificial magnetic conductors, and Bode matching limitations A clear explanation of the common misunderstanding of scan element pattern measurement, along with appropriate equations In-depth coverage of finite array Gibbsian models, photonic feeding and time delay, waveguide simulators, and beam orthogonality The book is complemented with a multitude of original curves and tables that illustrate how particular behaviors were derived from the author's hundreds of programs developed over the past forty years. Additionally, numerous computer design algorithms and numerical tips are included throughout the book to help aid in readers' comprehension. Phased Array Antennas, Second Edition is an ideal resource for antenna design engineers, radar engineers, PCS engineers, and communications engineers, or any professional who works to develop radar and telecommunications systems. It also serves as a valuable textbook for courses in phased array design and theory at the upper-undergraduate and graduate levels.
