The Hybrid Technique, which combines the Method of Moments with the Geometrical Theory of Diffraction, is used to investigate the radiation patterns of a UHF satellite antenna at various locations on a 28 in. by 28 in. square ground plane. Due to the diffraction which takes place at the edges of the ground plane, the radiation patterns are quite sensitive to the location of the antenna. It is concluded that, for the type of radiation coverage desired, it is best that the antenna be located close to one edge of the ground plane.
