Abstract
An antenna system is provided. The antenna system includes a circuit board. The antenna system further includes a first antenna structure and a second antenna structure. The first antenna structure is positioned between the circuit board and the second antenna structure such that the first antenna structure forms a ground plane for the second antenna structure. In addition, the first antenna structure is electrically coupled to the circuit board via a first conductive path. The second antenna structure is electrically coupled to the circuit board via a second conductive path extending through an opening defined by the first antenna structure.
