Download or read book A Limited scan Antenna Comprised of a Microwave Lens and Phased array Feed written by Robert V. McGahan and published by . This book was released on 1975 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Limited-scan antennas are finding increasing use in satellite communications and airport approach radars. Earlier attempts to achieve limited scan involved the use of parabolic lenses, zoning, and movable or dual-focus feeds. In the method described here, the main beam is scanned electronically by using a circular-arc phased array. The microwave lens is designed so that its back face satisfies the scanning condition. The beam is focused by shaping the front face of the lens to meet the required focusing condition and by varying the phase propagation of the lens. Two of the lenses studied were dielectric-loaded. A waveguide lens designed to scan in one dimension yielded experimental results that were good agreement with the theoretical predictions. Representative plots, and computer-generated farfield patterns of two topographically unique cases, are given.

Download or read book Apertures written by R. C. Hansen and published by Academic Press. This book was released on 2014-05-10 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microwave Scanning Antennas, Volume I: Apertures is a comprehensive account of phased arrays, multiple beam arrays, time domain and synthetic apertures, and adaptive antennas. Advances in continuous apertures and near field theory are discussed. Low noise and monopulse apertures, optical scanners, and large radomes are also covered, along with radio astronomy instruments and associated theory. Comprised of five chapters, this volume begins with an overview of aperture theory as well as aperture distributions and near field theory. The second and third chapters deal with mechanically steered and electronically scanned antennas, including monopulse antennas and optical scanners. The fourth chapter is devoted to radio astronomy instruments and techniques and encompasses both apertures and arrays, together with radio telescopes and antennas. The final chapter describes large radomes that are primarily used with aperture antennas. This book is intended for engineers who must understand narrow beam or high resolution antennas more deeply than from the system interfaces alone, and for undergraduate and graduate students in electronics who wish to complement their study of electromagnetics with the quantitative details of hardware applications.

Download or read book Aperture Antennas for Millimeter and Sub Millimeter Wave Applications written by Artem Boriskin and published by Springer. This book was released on 2017-09-05 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the technology of millimetre waves and Terahertz (THz) antennas. It highlights the importance of moderate and high-gain aperture antennas as key devices for establishing point-to-point and point-to-multipoint radio links for far-field and near-field applications, such as high data-rate communications, intelligent transport, security imaging, exploration and surveillance systems. The book provides a comprehensive overview of the key antenna technologies developed for the mm wave and THz domains, including established ones – such as integrated lens antennas, advanced 2D and 3D horn antennas, transmit and reflect arrays, and Fabry-Perot antennas – as well as emerging metasurface antennas for near-field and far-field applications. It describes the pros and cons of each antenna technology in comparison with other available solutions, a discussion supplemented by practical examples illustrating the step-by-step implementation procedures for each antenna type. The measurement techniques available at these frequency ranges are also presented to close the loop of the antenna development cycle. In closing, the book outlines future trends in various antenna technologies, paving the way for further developments. Presenting content originating from the five-year ESF research networking program ‘Newfocus’ and co-authored by the most active and highly cited research groups in the domain of mm- and sub-mm-wave antenna technologies, the book offers a valuable guide for researchers and engineers in both industry and academia.
