3. Using the Antenna Array Designer app in MATLAB, perform optimization to achieve a maximum gain by varying the inter-element spacing (min: 0.25λ, max: 1\) and phase shift (min: 0°, max: 360°) for a linear half-wavelength dipole array antenna. You may choose the number of elements between 4 to 8, the inter-element spacing between 0.25 to 1λ and the tilt angle between 20° to 60°. The center frequency can be any number between 1 to 10 GHz. With your report, also include the radiation pattern in both azimuth and elevation planes and state the angle (0) of the optimized maximum gain. 20
