Abstract
An antenna element, an antenna system, and a method for producing a signal using slot-coupled antenna elements are disclosed. The antenna element comprises an electrically conductive strip, a patch element, overlaying the electrically conductive strip, and a ground plane. The ground plane is coupled between the patch element and the electrically conductive strip and comprises an opening, at least a portion of the opening overlapping with at least a portion of the electrically conductive strip, wherein the opening and the electrically conductive strip can reflect incident radio frequency (RF) energy in a desired radiation pattern. A method in accordance with the present invention comprises illuminating a reflector with an RF signal emanating from a feed horn, wherein the reflector comprises at least one reflect array antenna element, and reflecting the RF signal from the reflect array element, wherein the reflect array element comprises an electrically conductive strip, a patch element, overlaying the electrically conductive strip, and a ground plane. The ground plane is coupled between the patch element and the electrically conductive strip and comprises an opening, at least a portion of the opening overlapping with at least a portion of the electrically conductive strip, wherein the opening and the electrically conductive strip assist in generating the desired radiation pattern.
