Directive diagrams of antenna arrays

Two systematic collections of directive amplitude diagrams are shown for arrays of 2 and of 16 identical antennae spaced at equal distances along a straight line with equal phase differences introduced between the currents in adjacent antennae, assuming that each antenna radiates equally in all directions in the plane of the diagram. Three diagrams show the effect of increasing without limit the number of antennae in a given interval. Two models show the effect of distributing the antennae over an area.
