Abstract:
An antenna system includes a planar substrate, a conductive ground plane, and an upper antenna element. The conductive ground plane is on the substrate. A slot that is free of conductive material extends through the ground plane to define a lower antenna element from a portion of the ground plane. The upper antenna element is spaced apart and overlies at least a portion of the lower antenna element. A first location of the upper antenna element is electrically connected to the ground plane and a spaced apart second location of the upper antenna element is electrically connected to an antenna feed element. The upper antenna element is configured to electrically resonate responsive to a defined RF signal. The lower antenna element is configured to resonate through capacitive coupling to the resonating upper antenna element.
