Radiation Patterns of an Antenna Mounted on the Off-Mid Section of an Ellipsoid.

Abstract

An efficient numerical solution for the high frequency radiation patterns of an Antenna mounted on the Off-Mid Section (theta (sub s) not equal to 90 degrees) of an Ellipsoid is studied in this report. The Uniform Geometrical Theory of Diffraction (UTD) is the basic approach applied here and the elliptic cone perturbation method is used to simulate geodesic paths on the ellipsoid surface. The radiation patterns obtained using this technique are compared to those for prolate spheroid-mounted antennas, which have shown good agreement with measured data. Exact agreement between both results for typical spheroid geometries confirms that radiation patterns for ellipsoid mounted antennas can be solved efficiently by this numerical technique.
