Book Synopsis An Investigation of Some Slow-Wave Conical Log-Spiral and Helical Antennas by : John D. Dyson
Download or read book An Investigation of Some Slow-Wave Conical Log-Spiral and Helical Antennas written by John D. Dyson and published by . This book was released on 1973 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first part of the report is concerned with the characteristics of conical spiral antennas constructed with zig-zag, i.e., slow-wave geometry, arms. This construction permits a reduction in size of approximately 15 percent below that required for the conventional antenna. It also increases the pattern beamwidth and lowers the characteristic impedance. In part 2, a 2 1/4-turn monofilar conical helix, fed at the base of the cone against an inner metal core, was investigated. This small circumference (approximately 1/4 wavelength) antenna can be made to be an axial radiating structure, while the conventional helix of this size radiates a maximum of energy broadside to the antenna axis.

Book Synopsis An Introduction to Electromagnetic Wave Propagation and Antennas by : Shane Cloude
Download or read book An Introduction to Electromagnetic Wave Propagation and Antennas written by Shane Cloude and published by Springer Science & Business Media. This book was released on 1995 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: This highly illustrated and accessible text will be an ideal introduction to the application of electromagnetics (EM) following an initial course in basic EM theory. The book covers the well established structure of elementary EM courses, beginning with Maxwell’s equations in integral form and developing the wave equation to show the essential properties of waves. In addition to providing a grounding in this traditional curriculum, the principal concern throughout is to make difficult concepts of electromagnetism more accessible. The adoption of time domain methods for this purpose is the book’s most important breakthrough, allowing the fundamentals of applied electromagnetics to be introduced with a clarity and simplicity not available through the conventional route. Another new aspect of this book is the integration of computational modelling methods with the standard theory of electromagnetic waves. The author presents a set of example programs written in the MATLAB language to support the ideas outlined in the text. The book is organized in a logical progression of ideas, starting with the general idea of wave motion and showing how the equations of electricity and magnetism lead to the existence of electromagnetic waves through the Maxwell’s equations. These ideas are then applied to simple accelerating charge models used in the engineering design of wire antennas. The concepts of resonance and antenna impedance are then treated from a time domain point of view. To reinforce the concepts of wave propagation, a chapter on computer modelling shows the rigorous procedures required to generate accurate numerical models of wave dynamics. The author extends these ideas to consider the properties of aperture antennas, showing how their important properties can be incorporated with the basic themes introduced earlier in the book. Finally, the important topic of wave scattering is introduced, once again from the point of view of time domain concepts.
