This case also shows a full 180° shift betweenelements provides a theoretical 90° shift in beam direction. In practice, with real element patterns ... plot the array factor for several array sizes.

First, in blue, the same 30° plot from Figure 11 in Part 1 is repeated. Next, the d/λ spacing is increased to 0.7 to show how the antenna pattern ... is called beam squint. Figure 5. Beam squint ...
