Question:

A linear array arranged along the z-axis consists of 12 equally spaced elements with d =2. Choose an appropriate incremental phase delay so as to steer the main beam to a direction 30 above the broadside direction. Provide an expression for the array factor of the steered antenna and plot the pattern. From the pattern, estimate the beam width.
