Abstract
An antenna system includes a substrate of a dielectric material. A conductive feed joins a number of conductive patches arranged in a line forming an array. The conductive patches are spaced from one another and the array is disposed on the substrate. The array has first and second sides. A first ground plane is disposed on the first side of the array and is spaced apart from the array. A number of conducting pillars ground the substrate to the first ground plane, and the conducting pillars define a second ground plane on the substrate. The array is configured to radiate a radiation pattern characterized by a first beam width in a first plane and a second beam width in a second plane perpendicular to the first plane, wherein the first beam width is wider than the second beam width.
