Abstract:
An antenna including:a ground plane that is electrically conductive having a first side surface;a first patch that is electrically conductive having:at least one edge; anda first side surface;a dielectric layer positioned between said first patch and said ground plane, said dielectric layer including:a first side surface in contact with said first side surface of said first patch; anda second side surface in contact with said first side surface of said ground plane;at least one tuning strip that is electrically conductive spaced from said at least one edge of said first patch and spaced from said ground plane by said dielectric layer;an RF feed connected to said first patch;switch means to electrically connect and disconnect RF energy between said at least one tuning strip and said first patch; anda control system coupled to said switch means that applies predetermined DC biases to cause said switch means to electrically connect and disconnect RF energy between said at least one tuning strip and said first patch.
