Patent ID: 7388546

Claim:
A portable electronic device having a double axial antenna structure, comprising: an electronic device having a main body, an operation unit and an image display unit, wherein the main body is used to accommodate the operation unit and the image display unit, and the image display unit is used to receive an electronic signal from the operation unit and display an image thereon; and a planar antenna, connected to the electronic device by a double axial connection element, for receiving an electromagnetic wave from the operation unit to generate the electronic signal, and said double axial connection element including: a rotation seat; a connection plate, pivotally-coupled to the planar antenna, and coupled to a substantially middle portion of the rotation seat by a pivot; a revolving shaft, having a first end and a second end, which rotate relative to each other, wherein the first end is fixed onto the electronic device and the second end connects to one end of the rotation seat; and an axial sleeve on the main body and connected to another end of the rotation seat by a pivot; wherein by the revolving shaft, the planar antenna is able to rotate about a first rotation axis, which is substantially parallel to a surface of the electronic device; and by the connection plate and the rotation seat, the planar antenna rotates about a second rotation axis, which is perpendicular to the first rotation axis; and wherein the planar antenna is rotatable about the first and the second rotation axis to adjust the quality and intensity of the received electromagnetic wave without moving the image display unit.
