Abstract:
An antenna assembly for use in a wireless communications device, the antenna assembly comprising:a conductive ground plane element; a high frequency resonator element having a conductive surface disposed a predetermined distance away from the ground plane element and having a ground end and a free end, said ground end being coupled to the ground plane element, said resonator element having a shunt feed point disposed on the conductive surface proximate the ground end; a low frequency resonator element having a conductive surface disposed a predetermined distance away from the ground plane element and having a ground end and a free end, said ground end being coupled to the ground plane element; and a conductive element functioning as high impedance transmission line, said conductive element coupling the low frequency resonator element to the high frequency resonator element, said conductive element having a first end and a second end, said first end being connected proximate to the shunt feed point and said second end being connected at the free end of the low frequency resonator element.
