AbstractA coplanar stripline antenna including a layer of dielectric material supporting a lower ground plane of conductive material on one side of the layer of dielectric material, a patch of conductive material on the other side of the layer of dielectric material, and an upper ground plane of conductive material on the other side of the layer of dielectric material and with the upper ground plane substantially surrounding and spaced from the patch of conductive material.Electrical signals are fed to the antenna between the patch of conductive material and the upper ground plane. A number of patches of conductive material may each be surrounded by the upper ground plane to form an antenna array and with the patches interconnected by coplanar stripline fed at a point equidistant from each patch.
