Abstract :
An efficient numerical solution for predicting high frequency radiation patterns of antennas on board complex bodies has been developed. These structures are modelled using NURBS (nonuniform rational B-spline) surfaces. The method efficiently combines geometric optics (GO) and the uniform theory of diffraction (UTD) approach with modern geometrical techniques.
