). Design a 10 × 8 (10 in the x-direction and 8 in the y) element uniform planar array so that the main maximum is oriented along thetag = 10°, phi o = 90°. For a spacing of d, = d, = 1/8between the elements, find the (a) progressive phase shift between the elements in the x and y directions (b) directivity of the array (c) half-power beamwidths (in two perpendicular planes) of the array.
