The equiangular spiral antenna at low frequencies
Abstract
The effect of the geometry of the equiangular spiral antenna on the lower cutoff frequency of operation is studied using the finite‐difference time‐domain method. Graphs are provided that allow calculation of the cutoff frequency from the desired performance and geometry. Additionally, the patterns of the antennas at cutoff are shown. © 2008 Wiley Periodicals, Inc.
