Abstract
An antenna configured to receive radiation at global navigation satellite system (GNSS) frequencies includes a substrate, a frontside patch arranged on a front side of the substrate, and a metamaterial ground plane. The metamaterial ground plane includes a plurality of backside patches and a cavity. The plurality of backside patches include a center backside patch surrounded in a radial direction by a plurality of intermediate backside patches. The center backside patch and the plurality of intermediate backside patches are arranged in a pattern that provides circular symmetry with respect to a center of the antenna. The cavity is coupled to the substrate, and the plurality of intermediate backside patches are electrically isolated from the cavity.
