The effect of a conducting half-plane sheet on the radiation patterns of dolph-chebyshev arrays

The radiation patterns of end-fire and broadside Dolph-Chebyshev arrays radiating in the presence of a conducting half-plane sheet have been calculated. Several values of the angle of incidence of these arrays with respect to the conducting half-plane sheet have been considered. These results are presented graphically and it can be seen that there is considerable distortion of the original pattern caused by the half-plane sheet. In general, when the main beam is directed toward the edge of the haft-plane sheet it is either partially reflected or split into several lobes.
