An antenna structure comprising a dielectric substrate layer and a patch layer laminated on top of the dielectric substrate layer, wherein the antenna structure is adapted to provide dual band coverage by combining a patch mode and a slot mode configuration. Exemplary embodiments of the present invention relate generally to a novel design for a compact, slot-loaded, proximity fed patch antenna structure. While the description herein describes frequency bands that are employed in global positioning system (GPS) implementations for exemplary calculations, the design may be equally applied to other applications where a compact, dual band antenna is desirable. Global navigation satellite systems (GNSS) such as GPS have become very commonly used devices.
