Patent number: 10396438Abstract: The present application provides an antenna system for use in an electronic device. The antenna system includes a conductive substrate. The antenna system further includes a conductive element, which extends along a length between two ends a distance away from the conductive substrate. An area between the conductive substrate and the conductive element form at least part of a loop which is internal to the antenna system. The antenna system still further includes a differential signal source coupled between two points along the length of the conductive element. Each of the two points are proximate a respective one of the two ends of the conductive element. The differential signal source is coupled to each of the two points via a high frequency blocking circuit.
