In one embodiment, the antenna structure includes a substrate having a first major face, a second major face, and a side face. The first major face may include a first laterally extending conductive structure extending along a first edge of the first major face of the substrate and a pronged conductive structure having a first prong extending from a portion of the laterally extending conductive structure towards a first corner of the substrate and a second prong extending from a portion of the laterally extending conductive structure towards a second corner of the substrate. The second major face includes a second laterally extending conductive structure with a conductive structure placing the conductive structures on the first major face in electrical communication with the conductive structures on the second major face.
