1. A multiple radiator element apparatus comprising:
- a plurality of three-dimensional radiator elements, each three-multiple radiator element comprising;
a plurality of sidewalls, at least one sidewall having one or more corrugations;
an enclosed radiating top surface substantially perpendicular to the plurality of sidewalls, the radiating top surface transmitting or receiving electromagnetic waves, the three-dimensional radiator elements arranged so that their radiating top surfaces are substantially parallel and so that at least one pair of adjacent three-dimensional radiator elements are separated by a dielectric gap between sidewalls of the respective three-dimensional radiator elements, the dielectric gap forming a waveguide that couples an electromagnetic interference with the electromagnetic waves; and
each radiator element further comprising a bottom side opposite from the radiating top surface, wherein at least one of the corrugations of one of the three-dimensional radiator elements interlaces with a corrugation of an adjacent three-dimensional radiator element without establishing a mechanical contact between the corrugations of the adjacent three-dimensional radiator element.

Abstract
A plurality of three-dimensional radiator elements, each radiator element transmitting or receiving electromagnetic waves by a radiating top side. The radiator elements are arranged so that their radiating top sides are substantially parallel and so that at least one pair of adjacent radiator elements are separated by a dielectric gap between sidewalls, the gap behaving like a waveguide which couples electromagnetic interferences with the electromagnetic waves. The adjacent radiator elements further comprise a structure to suppress the coupling effect without establishing a galvanic contact with its adjacent radiator element.
