Download or read book Radiation from Dielectric Loaded Waveguide Fed Aperture Antennas written by Martin D. Bradshaw and published by . This book was released on 1971 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Theoretical and experimental studies of the radiation pattern and input admittance of dielectric loaded waveguide fed aperture antennas are presented. The model consists of a waveguide fed, dielectric loaded aperture whose outer surface is flush with an infinite, perfectly conducting ground plane. The aperture and ground plane are covered by a dielectric layer. The window and the covering layer may be inhomogeneous in the direction of propagation. The analysis makes use of a mode-matching process that permits the effects of higher order modes to be taken into account in the dielectric loaded aperture section and in the covering layer. The window and layer are represented by an arbitrary number of inhomogeneous, lossy, dielectric slabs, each with slightly different permittivities. Collaction (point-matching) techniques are used to match boundary conditions at each interface within the dielectric loaded aperture section and two-dimensional Fourier transforms are used to match boundary conditions at each interface in the covering layer. Matrix techniques are used to handle an arbitrary number of layers in either region. A large number of experimental measurements of input admittance and far-field radiation pattern measurements are presented for three different aperture configurations, with and without a covering dielectric layer. A computer program is described that can handle the computations. The program is written in FORTRAN IV for a Control Data Corporation 6600 machine. Computed values of input admittance and far-field radiation patterns are presented. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Dielectric Resonator Antennas A detailed guide to dielectric-based techniques for antenna array design and construction Dielectric designs, which transmit electricity without conducting it, have in recent decades been increasingly incorporated into antenna arrays. The resulting Dielectric Resonator Antennas (DRAs) provide significant benefits over metal antennas, avoiding conduction loss and increasing efficiency. Dielectric elements can also be incorporated into metal antennas to improve performance. Dielectric Resonator Antennas provides an introduction to dielectric-based techniques for manufacturing antenna arrays. It supplies guidelines for identifying dielectric antenna designs (as opposed to metal ones), describes recent developments in dielectric antenna technology, and points toward potential areas of future growth and development. Readers will also find: Cutting-edge DRA applications in microwave and millimeter-wave communications Detailed discussion of array types including wideband, high-gain, high efficiency, and more Instructions for fabricating dielectric antenna arrays and assessing tolerance levels Dielectric Resonator Antennas is ideal for researchers and students in electrical engineering, as well as for engineers and others working in wireless communications.

Download or read book Design of Nonplanar Microstrip Antennas and Transmission Lines written by Kin-Lu Wong and published by John Wiley & Sons. This book was released on 2004-04-07 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: A one-stop reference to the design and analysis of nonplanar microstrip structures. Owing to their conformal capability, nonplanar microstrip antennas and transmission lines have been intensely investigated over the past decade. Yet most of the accumulated research has been too scattered across the literature to be useful to scientists and engineers working on these curved structures. Now, antenna expert Kin-Lu Wong compiles and organizes the latest research results and other cutting-edge developments into an extensive survey of the characteristics of microstrip antennas mounted on canonical nonplanar surfaces. Demonstrating a variety of theoretical techniques and deducing the general characteristics of nonplanar microstrip antennas from calculated results, Wong thoroughly addresses the problems of cylindrical, spherical, and conical structures and gives readers powerful design and optimization tools. Up-to-date topics range from specific applications of spherical and conical microstrip arrays to the curvature effects on the analysis of cylindrical microstrip lines and coplanar waveguides. With 256 illustrations and an exhaustive list of references, Design of Nonplanar Microstrip Antennas and Transmission Lines is an indispensable guide for antenna designers in wireless and personal communications and in radar systems, and an invaluable reference for researchers and students interested in this important technology.
