An antenna array comprising means for suppressing the coupling effect in the dielectric gaps between its radiating elements without establishing galvanic contacts

摘要

An antenna array comprising: a plurality of elements (1, 22, 23, 24, 25, 26, 27) radiating three dimensions, each radiating element of three dimensions a plurality of side walls conductive and radiant upper surface comprising conductive perpendicular to the plurality of sidewalls, including radiant upper surface a patch antenna radiating that is configured to transmit or receive electromagnetic waves, the radiating elements of three arranged dimensions so being that their radiating top surfaces are in the same plane and at least a pair of radiating elements of three adjacent dimensions are separated by a dielectric gap between sidewalls of the respective radiating elements of three dimensions, forming the dielectric hollow waveguide configured to cause by a coupling effect electromagnetic interferences with the waves wherein each one or said at least one pair of radiating elements adjacent three dimensions comprises means to suppress the coupling effect without establishing a galvanic contact with its radiant three adjacent dimensional element, said means comprising corrugations (2, 3, 4, 5 , 6, 7, 8, 9, 10) arranged on the side wall facing the gap, being the corrugations arranged so that the corrugations of one of the radiating elements of three dimensions are interlocked with the corrugations of the element (1, 22, 23, 24, 25, 26, 27) adjacent radiant three dimensions, without establishing a mechanical contact.
