Abstract

An algorithm is developed based on uniform geometric theory of diffraction (UTD) for the analysis of an antenna mounted on a rocket shaped structure. Yu and Burnside (1972) elevation plane theory is extended, so that analysis can be done even if the source is located on other parts of the structure. The theory is validated with Ryan´s (1972) result which is based on estimation of magnetic edge currents at junctions. The radiation patterns in the roll and azimuth planes are obtained using standard curved surface diffraction theory and agree well with published theoretical or experimental results.
