Patent ID: 8154457

Claim:
A multiple radiator element apparatus comprising: a plurality of three-dimensional radiator elements, each three-dimensional radiator element comprising: a plurality of sidewalls, at least one sidewall having at least one of a rounded groove and a concavely-dug corner edge; a radiating top side substantially perpendicular to the plurality of sidewalls, the radiating top side transmitting or receiving electromagnetic waves, the three-dimensional radiator elements arranged so that at least one pair of adjacent three-dimensional radiator elements are separated by a gap and so that their radiating top sides are in a substantially same plane, the gap forming a waveguide that couples by a coupling effect an electromagnetic interference with the electromagnetic waves; and each radiator element further comprising a bottom side opposite from the radiating top side; and the multiple radiator element apparatus further comprising a metallic cylinder having a top end and a bottom end opposite from the top end, the top end having a conductive head in galvanic contact with the radiating top sides of the adjacent three-dimensional radiator elements, the metallic cylinder having longitudinally cut slots so as to form a resilient cylindrical body, wherein the resilient cylindrical body is inserted in the gap at a location where at least two of the rounded grooves or the concavely-dug corner edges face each other, wherein the metallic cylinder suppress the coupling effect, while allowing for a thermal expansion of adjacent three-dimensional radiator elements.
