A simple, accurate method is presented for calculating the H-plane radiation pattern of a dipole antenna mounted parallel to a finite rectangular ground screen. The solution is valid for ground screens which are large in the dimension parallel to the dipole. The H-plane radiation pattern of the antenna is predicted from an approximate solution for the field of an electric line source parallel to a perfectly con¬ ducting strip of infinite length and finite width. A simple solution of the strip problem is obtained which is useful for all but very narrow strips. Computed patterns are presented for a wide range of ground plane widths and dipole spacings. Comparisons with experimental results indicate that the solution is accurate for the complete range of parameters of engineering interest.
