Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this research has been to investigate the behavior of electrically thick cylindrical antennas by obtaining experimental data on a physics counterpart of a theoretical dipole antenna model. The experimental apparatus, consisting of a monopole antenna driven over an image place by means of a coaxial line, was designed to allow for the measurement of antenna characteristics over a 0.1

This book was released on 1967 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current distribution and input admittance of an electrically thick, tubular, monopole antenna driven by a coaxial transmission over a ground plane has been investigated and compared with theoretical results. When the circumference of the antenna is comparable to a free-space wavelength, this experiment verifies that the theoretical model of a tubular dipole antenna with a delta-function excitation only on the outside surface describes the experimental situation more properly than the conventional model of a delta-function excitation on both outside and inside surfaces of the antenna.

Download or read book Monopole Antennas on Electrically Thick Conducting Cylinders Volume I Experimental Design Admittance and Impedance Measurements written by Lee J. Cooper and published by . This book was released on 1975 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: A summary of research in electromagnetic phenomena is presented. This review consists of a logically arranged outline of topics with brief summaries and references to the relevant Technical Reports followed by a listing of all Technical Reports and publications resulting from these investigations. The main headings are: Antennas; Coupled Antennas and Arrays; Antennas and Waves in Dielectric, Conducting, or Plasma Media; and Miscellaneous Topics. The bulk of this two-volume report is comprised of the results of a rigorous experimental study of monopole and dipole antennas modified to have electrically thick conducting cylinders at their centers. This configuration has many practical applications including antennas on shipboard or spacecraft where the satellite, rocket frame, or ship's hull has physical dimensions on the order of a wavelength. Since no exact analytical formulation was available, the experimental design was precisely constructed to give the admittance, impedance, distributions of current and charge, and radiation patterns to a high degree of experimental accuracy. In this, the first volume of the report, a complete description of the experimental design, apparatus, and system of calibration is given along with the measured admittance and impedance results.

Book excerpt: The results of a rigorous experimental study of monopole and dipole antennas modified to have electrically thick conducting cylinders at their centers are presented in this two-volume report. This configuration has many practical applications including antennas on shipboard or spacecraft where the satellite, rocket frame, or ship's hull has physical dimensions on the order of a wavelength. Since no exact analytical formulation was available, the experimental design was precisely constructed to give the admittance, impedance, distributions of current and charge, and radiation patterns to a high degree of experimental accuracy. Distribution data were fitted with a least-squares polynomial which was used for normalization purposes and to compute the radiation fields. In this, the second volume of the report, the measured current and charge distributions are given along with radiation patterns obtained from direct measurements and calculated from the measured currents. The report closes with a general interpretation of the results and a discussion of their application to practical situations. Attention is directed to Volume I for a complete description of the experimental design, apparatus, and system of calibration, as well as measured admittance and impedance results.
