This book was released on 1974 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: The combination of a linear antenna and a slot antenna can be used to provide a relatively isotropic radiation pattern when the dipole is perpendicular to the plane of the slot. The theoretical far field radiation pattern of a dipole flanked by a two-element array of slot antennas is formulated. The fields for a variety of relative phasings between the elements of the combination antenna are calculated and the degree of approximation to an isotropic source in the sense of the total field noted. An experimental antenna was fabricated and the radiated fields measured with good agreement found with the theoretical formulas. (Author).

Download or read book Theoretical and Experimental Investigation of Some Slot Antenna Array Problems written by R. S. Elliott and published by . This book was released on 1981 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effect of metallic fences on mutual coupling between slots of a slot antenna is studied. A model solution has been obtained whereby the fence is modelled as a thin half elliptic cylinder. This model allows for thickness to be taken into account and provides exact solutions to mutual impedance computations. The geometrical theory of diffraction has been adopted to analyze an exceedingly thin fence, when the slot antennas are not too close to the fence. Design procedures for longitudinal and traverse stripline-fed slots have been developed. A design procedure for such slot arrays requires knowledge of the mutual coupling relation as well as the self-impedance properties of a slot. Preliminary design equations are reported in this document. (Author).

Download or read book Dielectric Resonator Antennas written by Kwai Man Luk and published by Research Studies Press Limited. This book was released on 2003 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of dielectric resonator as a resonant antenna was proposed in 1983. Due to the absence of metallic loss, the dielectric resonator antenna (DRA) is highly efficient when operated at millimetre wave frequencies. With the use of high dielectric constant material, the DRA can also be used as a small and low profile antenna operated at low microwave frequencies. Low cost dielectric materials are now easily available commercially, encouraging more antenna engineers to design communication systems with DRAs.

Download or read book Spaceborne Antennas for Planetary Exploration written by William A. Imbriale and published by John Wiley & Sons. This book was released on 2006-08-04 with total page 594 pages. Available in PDF, EPUB and Kindle. Book excerpt: JPL spacecraft antennas-from the first Explorer satellite in 1958 to current R & D Spaceborne Antennas for Planetary Exploration covers the development of Jet Propulsion Laboratory (JPL) spacecraft antennas, beginning with the first Explorer satellite in 1958 through current research and development activities aimed at future missions. Readers follow the evolution of all the new designs and technological innovations that were developed to meet the growing demands of deep space exploration. The book focuses on the radio frequency design and performance of antennas, but covers environmental and mechanical considerations as well. There is additionally a thorough treatment of all the analytical and measurement techniques used in design and performance assessment. Each chapter is written by one or more leading experts in the field of antenna technology. The presentation of the history and technology of spaceborne antennas is aided by several features: * Photographs and drawings of JPL spacecraft * Illustrations to help readers visualize concepts and designs * Tables highlighting and comparing the performance of the antennas * Bibliographies at the end of each chapter leading to a variety of primary and secondary source material This book complements Large Antennas of the Deep Space Network (Wiley 2002), which surveys the ground antennas covered in support of spacecraft. Together, these two books completely cover all JPL antenna technology, in keeping with the JPL Deep Space Communications and Navigation Series mission to capture and present the many innovations in deep space telecommunications over the past decades. This book is a fascinating and informative read for all individuals working in or interested in deep space telecommunications.
