An array theta sub 0 equals 90 degrees dived the z axis in such a way that the three element array appears on the top and three element array appears on the bottom. An array oscillates from theta sub 0 equals 30 degrees to theta sub 0 equals 150 degrees. The array is steerable from theta sub 0 equals 30 degrees to theta sub 0 equals 150 degrees. The elements are placed at a distance of d along the z axis. The horizontal axis labeled, theta sub 0 equals 90 degrees (broadside).
