1. An antenna comprising:

  • a support member; and

    an arrangement of a plurality of at least three separate electromagnetic wave radiation elements symmetrically distributed in a prescribed pattern on said support member so as to define a prescribed radiating aperture of the antenna and being spaced apart at a perimeter of said arrangement from a conductive member, which conductive member provides a conductive reference plane for said elements adjacent to the perimeter of the arrangement of said elements on said support member; and

    whereineach of said elements includes means for electrically coupling that respective element, at a first edge portion thereof lying in said prescribed radiating aperture and adjacent to said conductive member, to a respective signal coupling device for controlling the electromagnetic wave radiation characteristic of that element, and wherein each of said elements has a second, rectilinear edge portion thereof spaced apart from and capacitively coupled to a rectilinear edge portion of an adjacent element in an interior region of said arrangement.
