Abstract-An asymptotic solution of a 3D vector diffraction problem for a vibrator system placed over a rectangular perfectly conducting screen of finite dimensions is obtained in the framework of the uniform geometrical theory of diffraction (UGTD) using the asymptotic expressions for the impedance vibrator currents. The system consists of two orthogonally crossed vibrators with equal dimensions but different surface impedances. The vibrators are excited in-phase. An algorithm and respective software for computing the directional, power and polarization characteristics of the radiation field of this antennas system are developed. The conditions required to form a circularly polarized radiation with a maximally attainable directivity in the normal direction to the screen are determined depending on the screen dimensions and the distance between the vibrators and the screen.

On the basis of a method of the uniform geometrical theory of diffraction the far field of a vertical half-wave electric dipole located arbitrarily above a metal plane with a rectangular thin ledge is determined in all space of observation. The directive patterns of the orthogonal components of the vector of electric field intensity, radiation resistance, the directive gains of the dipole and factor of protective action of a ledge in the direction of normal to it were calculated versus the position of the dipole, as well as the ledge and the plane parameters.
