Patent ID: 6982676

Claim:
A multiple slot antenna comprising: (a) a first plurality of cards defining a plurality of slots therebetween for radiating electromagnetic energy therefrom, each card having conductive material layer disposed on at least one side of a dielectric material layer, the conductive material layer on at least one side of each card in said first plurality of cards forming a plano-convex Rotman lens with a plurality of parallel conductors emanating therefrom; (b) a second plurality of cards arranged with edges aligned orthogonally to the dielectric material layers in the first plurality of cards, the second plurality of cards each having conductive material formed on at least one side of a planar dielectric element, the conductive material on at least one side of each planar dielectric element of the second plurality of cards forming a convex-convex Rotman lens with a plurality of parallel conductors emanating therefrom; and (c) the plurality of parallel conductors emanating from the plano-convex Rotman lens on a given card in first plurality of cards mating with one of the parallel conductors emanating from each convex-convex Rotman lens in the second plurality of cards.
