Helical and Spiral Antennas: A Numerical Approach (Electromagnetic Series)

This monograph, the result of five years of research, presents a fully descriptive account of antennas and scatterers for a circularly polarized wave. The author presents the radiation characteristics of these antennas and scatterers with emphasis on their engineering aspects. Numerical examples treating a system consisting of wires and slots are described and thoroughly analyzed. The first chapter covers numerical methods and techniques for antenna analysis, followed by chapters describing the square spiral antenna, two-wire round spiral antenna, spiral antenna with two off-center sources, polarization diversity of Archimedian spiral antenna, helical antenna of endfire mode, helical antenna of backfire mode, conical helix antenna, and wire scatterer for a circularly polarized wave.
