New formulations for mutual coupling computations of antennas on general quadric cylinders and surfaces of revolution

Microstrip and slot antennas are often used in aerospace vehicles because of their advantages of simplicity in construction, lightweight and their ability to conform to the shape of the space-borne structures. In practice, a large number of aerospace bodies or their significantly scattering portions can be conveniently approximated by Quadric Surfaces of Revolution (QUASORs) or Quadric Cylinders (QUACYLs). The theoretical performance of the antennas in presence of these structures is amenable to analysis using the ray-theoretic techniques such as the Uniform Theory of Diffraction (UTD).
