Directive and Polarization Patterns of Finite-Size Corner Antenna with Circularly Polarized Field

Within the frames of the uniform geometrical diffraction theory method the 3D vector problem of radiation of a finite size corner antenna excited by a tilted half-wave electric dipole has been solved and the effective software were developed. The spatial directive and polarization patterns of a corner antenna at optimum sizes as well as at dipole slope angle providing the circularly polarized radiation along the normal to the corner aperture with optimized directive gain are investigated. It is shown that the circularly polarized field takes place also in the angular sector of thirty degrees relative to the corner normal.
