Analysis on wire antennas mounted on complex conducting objects using hybrid curvilinear and planar geometries

A method of moments solution to the radiation and scattering problem of wire antennas mounted on complex conducting objects is presented. Curvilinear triangular patches are chosen to discretize the surface of the objects and curvilinear Rao-Wilton-Glisson (RWG) basis function has been used to model the surface current. The pulse and linear Costa basis functions defined on planar geometry is used to discretize wire antenna and junction part respectively. The typical numerical example demonstrates the validity and efficiency of this method.
