Zusammenfassung:	Apparatus for radiating and/or receiving microwaves and comprising one radiator group with u building blocks with u being an even number, whereinsaid radiator group has a sandwich-layout comprising a structured layer with q integrated cavities on one side face, with q being an even number, and a structured metal layer covering at least part of said one side face,said u building blocks are structurally identical,said metal layer is structured so that each of said u building blocks comprises a suspended patch-shaped element, which is cavity-backed by one of said q integrated cavities,the shape and size of said patch-shaped elements is defined by boundary slots of said metal layer,said at least one radiator group has a common, central feed point as interface for a hollow waveguide, andwherein said apparatus comprises a hollow waveguide or a waveguide flange being connected to said central feed point.
