Abstract
Official abstract text for this publication.
An antenna assembly includes: a substrate material supporting a plurality of substantially parallel conductive layers; a ground plane defined by a first conductive layer; an grid of antenna elements, each antenna element including: an excitation patch defined by a second conductive layer, and configured for connection to a controller port; a first annular radiative element defined by a third conductive layer; a second annular radiative element defined by a fourth conductive layer; wherein the excitation patch, the first annular radiative element, and the second annular radiative element are disposed in a stack with an axis perpendicular to the first conductive layer.

The invention claimed is: 1 . An antenna assembly, comprising: a substrate material supporting a plurality of substantially parallel conductive layers; a ground plane defined by a first conductive layer; an grid of antenna elements, each antenna element including: an excitation patch defined by a second conductive layer, and configured for connection to a controller port; a first annular radiative element defined by a third conductive layer; a second annular radiative element defined by a fourth conductive layer; wherein the first annular radiative element and second annular radiative element are cross-shaped; and wherein the excitation patch, the first annular radiative element, and the second annular radiative element are disposed in a stack with an axis perpendicular to the first conductive layer. 2 . The antenna assembly of claim 1 , wherein each antenna element further comprises: a second excitation patch defined by the second conductive layer, the second excitation patch being orthogonal to the first excitation patch. 3 . The antenna assembly of claim 1 , further comprising a grounded boundary structure surrounding each of the antenna elements in the grid. 4 . The antenna assembly of claim 3 , wherein the boundary structure is defined by the second conductive layer. 5 . The antenna assembly of claim 1 , wherein a perimeter of the first annular radiative element is smaller than a perimeter of the second annular radiative element. 6 . The antenna assembly of claim 1 , wherein each antenna element further comprises: a third annular radiative element defined by a further conductive layer. 7 . The antenna assembly of claim 1 , wherein the grid includes a four-by-four grid of antenna elements. 8 . An antenna element, comprising: a ground plane defined by a first conductive layer; an excitation patch defined by a second conductive layer, and configured for connection to a controller port; a first annular radiative element defined by a third conductive layer; a second annular radiative element defined by a fourth conductive layer; wherein the first annular radiative element and second annular radiative element are cross-shaped; and wherein the excitation patch, the first annular radiative element, and the second annular radiative element are disposed in a stack with an axis perpendicular to the first conductive layer.
