Abstract:

An efficient numerical solution for the high frequency radiation patterns of an Antenna mounted on the Mid-Section thetaS 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 cylinder 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 geometry confirms that radiation patterns for ellipsoid mounted antennas can be solved efficiently by this numerical technique. Author
