Abstract
An array antenna with dual polarization elements is provided. Each dual polarization element comprises a first sub-element and a second sub-element, each of which comprises a radiator that is embodied in and/or on a planar member and a balanced feed for the radiator that divides the radiator into two sections that that are mirror images of one another relative to a plane that passes through the balanced feed structure and is perpendicular to the planar member. Further, the radiator of the first sub-element is positioned to lie in an isolation plane associated with the second sub-element. Two such elements are positioned with respect to one another so that the planar members associated with the first elements are coplanar.
