Demo 9.4: Beam Steering

The array pattern of an equally-spaced linear array can be steered in direction by applying linear phase across the array as shown. Note that =kd cos ₀, with ₀ measured from the +z-axis.

Display the array pattern for the following values of the beam center angle:   0=90o(broadside)   0=60o(30o above x-axis)   0=30o(60o above x-axis)   0=120o(30o below x-axis)   0=150o(60o below x-axis)
