Microwave Antenna

The latest text in the Wiley Series in Microwave and Optical Engineering The first comprehensive resource on planar antenna designs Planar antennas are the newest generation of antennas, boasting such attractive features as low profile, light weight, low cost, and ease of integration into arrays. These features make them ideal components of modern communications systems, particularly in cellular and WLAN applications. Consequently, many novel designs of planar antennas for related applications have come into being within the last two to three years. Until now these designs were only accessible to current and prospective antenna designers through journal articles, conference papers, and patent descriptions. Planar Antennas for Wireless Communications organizes today’ s most important planar antenna designs into one easy-to-use reference. In this, the latest addition to the Wiley Series in Microwave and Optical Engineering, the author presents more than seventy advanced planar antenna designs, along with detailed design considerations and experimental results, including: PIFAs for internal mobile phone antennasVery-low-profile monopoles for internal mobile phone antennasBase-station antennas for cellular systemsPlanar antennas for WLAN applicationsDR antennas for wireless communicationsIntegration of antennas for different operating bands Each chapter features a multitude of illustrations for the geometries and experimental results of the featured designs, as well as a complete list of related references for further study, making the book an invaluable design resource for antenna scientists and engineers alike.

The first complete guide to phased array design and theory in more than thirty years destined to become the standard reference in the field well into the twenty-first century The past twenty years have witnessed significant breakthroughs in our understanding of the principles behind phased array antennas and in their design and application. Yet not since R. C. Hansen's 1966 classic, Microwave Scanning Antennas, has there been a comprehensive reference in the field. Phased Array Antennas fills the gap in the professional literature. Phased Array Antennas is geared to the interests of both the practicing design engineer and the antenna array analyst. Written by an internationally recognized expert with more than four decades of experience in the field, it offers detailed coverage of all practical and theoretical aspects of phased arrays from quantization lobes and low sidelobe pattern design and measurement to superdirectivity and HTS antennas and frequency scanners. It also provides in-depth coverage of topics such as finite array Gibbsian models, photonic feeding and time delay, waveguide simulators, and beam orthogonality. A multitude of original curves and tables show particular behaviors derived from hundreds of programs developed by the author over the past twenty years, and numerous computer design algorithms and numerical tips are found throughout the book. Phased Array Antennas is an indispensable tool-of-the-trade for antenna design engineers, radar engineers, PCS engineers, and communications engineers. It also serves as a complete text in phased array design and theory for advanced undergraduate-and graduate-level courses in electronics and communications.

Antenna gain - Antenna gain is the measurement of an antennas ability to amplify the incoming microwave signals in a particular direction, compared with the sensitivity of an isotropic antenna in any direction, or a dipole antenna in the equatorial direction. The two measurements are measured in decibels and denoted by dBi and dBd respectively.

Fractal antenna - A fractal antenna is an antenna that uses a self similar design to maximize the length, or increase the perimeter (on inside sections or the outer structure), of material that can receive or transmit electromagnetic signals within a given total surface area. For this reason, fractal antennas are very compact, are multiband or wideband, and have useful applications in cellular telephone and microwave communications.

Horn Antenna - The Horn Antenna, at Bell Telephone Laboratories in Holmdel, New Jersey, is listed as a National Historic Landmark because of its association with the research work of two radio astronomers, Arno Penzias and Robert Wilson. In 1965 while using the Horn Antenna, Penzias and Wilson stumbled on the microwave background radiation that permeates the universe.

Discovery of cosmic microwave background radiation - This article concerns the accidental discovery of cosmic microwave background radiation. Although predicted by earlier theories, it was first found accidentally by Arno Penzias and Robert Woodrow Wilson as they experimented with the Horn Antenna.
