Directional and polarization characteristics of crossed impedance wire dipoles with square screen

On the base of the uniform geometric diffraction theory method, using the asymptotical expression for a current of an impedance wire dipole located over a perfectly conducting plane, the fast active algorithms and programs are developed for computations of the directional and polarization characteristics of radiation produced by two synphasely excited crossed dipoles placed in parallel to a square screen. The analysis is carried out in the cases of the dipoles with surface resonant uniform distributed impedances, and with impedances, which provide the circular polarization in the normal direction to the screen.
