Abstract: The present application provides an antenna system for use in an electronic device having wireless communication capabilities. The antenna system includes a conductive ground structure and one or more arms. Each arm of the one or more arms having two ends and a conductive path between the two ends, where a first one of the two ends of the arm is coupled to the conductive ground structure. From the first end and along the conductive path, the arm extends along an edge of the conductive ground structure a distance away from the conductive ground structure, where the distance between the edge of the conductive ground structure and the corresponding conductor path of the respective one of the one or more arms encompasses an area forming a loop which is internal to the antenna system. The antenna system further includes a secondary conductive structure, coupled to the conductive ground structure, which extends into the area forming the loop which is internal to the antenna system.

Abstract: The present application provides a housing for an electronic device sub-assembly for use in an electronic device having wireless communication capabilities. The electronic device sub-assembly includes a loop antenna structure having a conductive ground structure, and a conductive loop element separate from the conductive ground structure. The conductive loop element has two ends and a conductive path, which extends between the two ends a distance away from the conductive ground structure. The conductive loop element is coupled to the conductive ground structure at each of the two ends, and the distance that the conductive path of the conductive loop element extends away from the conductive ground structure encloses an area forming a loop which is internal to the loop antenna structure. The electronic device sub-assembly further includes a signal source coupled between the conductive loop element and the conductive ground structure across the loop for applying a drive signal.
