Analysis and Design of Special Antenna Configurations
Abstract
A new reaction solution was formulated for three-dimensional wire antennas located in free space or over a ground plane, using a piecewise- sinusoidal expansion for the unknown current distribution on the antenna. A set of linear equations was developed for solution by a digital computer. Impedance, radiation efficiency, field patterns, gain, and directivity can be calculated. Computer programs based on this new formulation were used to determine the impedance versus frequency for various loop antennas. Verification of the calculations with experimental results showed that the technique is highly accurate not only for the impedance but also for the current distribution. Calculated and measured results for several three-dimensional dipoles and a square halo antenna are also given.
