Abstract : The radiation patterns, in the elevation plane, of airborne antennas mounted on the aircraft fuselage have been analyzed by modern diffraction theory including wedge diffraction theory and creeping wave theory. It is found that the fuselage shape has a dominant effect on the elevation patterns. In order to analyze a general convex shape, a new approach, 'section matching method', has been developed in which the fuselage profile is described by a set of points. This new method is applied to some general geometrical shapes which approximate aircraft fuselage. The composite elliptical cylinder is the most general model considered. The validity of this method has been verified by modal one more rigorous GTD solutions. (Author)
