1. An antenna array for providing effective directional gain comprising:

  • a supporting structure;

    a plurality of antenna elements, said elements positioned on said support structure to define at least tow sub-arrays, each sub-array including one central antenna element secured to said structure and six planetary antenna elements connected to said structure and spaced from said central antenna element in an arrangement such that said planetary antenna elements define a regular hexagon about said central antenna element, wherein each of said sub-arrays may selectively provide, through the operative cooperation and contribution of its planetary antenna elements and central antenna element, effective directional gain about an axis passing through the hexagon defined by the planetary antenna elements of the sub-array;

    at least one amplifier, wherein the number of said amplifiers is less than the number of said antenna elements; and

    means for selectively connecting at least said one amplifier to one of said antenna elements in at least each of said two sub-arrays.
