Abstract:
1. A mobile electronic device, comprising: a housing having a front, a back, and a perimeter sidewall extending between the back and the front; an electrical ground member housed within the housing and spaced from the perimeter sidewall; an antenna mounted on the electrical ground member; a conductive ring extending around the perimeter sidewall of the housing; and an insulating fastener connected to a surface of the conductive ring and extending substantially parallel to a portion of the conductive ring; a transmission line disposed on the insulating fastener and extending substantially parallel to the portion of the conductive ring to electrically isolate the transmission line from the conductive ring; a first short electrically connected to the conductive ring and to the transmission line at a first point along a length of the transmission line; and a second short electrically connected to the electrical ground member and to the transmission line at a second point along the length of the transmission line; wherein the transmission line tunes the antenna by transforming an impedance between the electrical ground member and the antenna when the antenna is in operation.
