Bandwidth of the Uniform Helical Antenna

摘要

This incestigation covered antennas of between 3 and 10 turns and pitch angles of 5°and 24°. At the same time, sufficient analysis was carried out to given an adequate understanding of the operation of the antenna in terms of inward-and outward-traveling waves along the conductor. These investigations were completed by 1950.nThe object of the present investigation was to carry this out, and as a result, new information is available about the limits of the helical pitch angle which may be employed, and about the bandwidth of helical antennas as long as 10 wavrlengths.
