AN ARRAY ANTENNA COMPRISING MEANS TO SUPPRESS THE COUPLING EFFECT IN THE DIELECTRIC GAPS BETWEEN ITS RADIATOR ELEMENTS WITHOUT ESTABLISHING GALVANIC CONTACTS

摘要

There is disclosed an apparatus comprising a plurality of three-dimensiona l radiator elements, each radiator element transmitting or receiving electromagnetic waves by its radiating top side. The radiator elements are arranged so that their radiating top sides are 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 induces by a coupling effect electromagnetic interferences with the waves. Each of said adjacent radiator elements comprises means to suppress the coupling effect without establishing a galvanic contact with its adjacent radiator element. Application : detection, telecom.
