A broadband phased antenna is comprised of multiple patches which are dirly feed. The multiple patches provide the broadband patch antenna having overlapping narrow frequency bands and comprise a ground-plane element, multiple antenna elements, multiple dielectric layers, an RF feed line, and a feed arrangement. The ground-plane element has predetermined length and width dimensions and an aperture therein at a predetermined location near its center. The multiple antenna elements have an uppermost antenna element. The multiple dielectric layers are respectively interposed between and separate the multiple antenna elements into a stacked arrangement having odd and even numbered antenna elements.

[ What is claimed is:] [1.] A broadband antenna comprising:a ground-plane element with predetermined length and width dimensions and having an aperture therein at a predetermined location near its center;a plurality of antenna elements having an uppermost antenna element;a plurality of dielectric layers respectively interposed between and separating said plurality of antenna elements into a stacked arrangement having alternating odd and even numbered antenna elements, and further separating said stacked arrangement from said ground-plane element, said stacked arrangement having an odd numbered element nearest said ground-plane element;an RF feed line having an outer conductor and a center conductor, the feed line protruding through said aperture of said ground-plane element, said RF feed line extending upward to a feed point that is about half the distance between said ground-plane element and said uppermost antenna element; anda feed arrangement having said outer conductor comprising a first bus and said center conductor comprising a second bus, said first bus being connected to said ground-plane element and to every even numbered antenna element and said second bus being connected to every odd numbered antenna element.
