Patent number: 6424311Abstract: A dipole antenna for selecting an antenna polarization plane of the strongest polarization energy includes at least two dipole antenna elements (1, 2) arranged perpendicularly to each other to form a single antenna, a PCB (3), and two feeding lines (4). Each dipole antenna element includes two T-shaped dipole arms (11, 12). This structure makes use of two planes of the XZ-plane, XY-plane and YZ-plane, and also makes the dipole antenna more compact. The antenna obtains optimum polarization energy by selecting the strongest energy plane. This achieves maximized radiation efficiency under any particular orientation of the dipole antenna. The strongest energy plane is selected by controlled switching, by means of dual-fed signal mode. The dipole arms of each dipole antenna element are disposed on opposite surfaces (31, 32) of the PCB, to minimize interference.Type: GrantFiled: March 20, 2001Date of Patent: July 23, 2002Assignee: Hon Ia Precision Ind.

Patent number: 6342868Abstract: A stripline PCB dipole antenna for use in an electronic device includes a substrate (3), a first dipole antenna (1), a second dipole antenna (2), a first feeder apparatus (41), and a second feeder apparatus (42). The first and second dipole antennas are generally T-shaped, are disposed on opposite surfaces of the substrate, are perpendicular to each other, and are fed through the first and second feeder apparatuses respectively. The first and second feeder apparatuses feed the antennas near respective edges of the substrate, to reduce any adverse influences that their wiring paths may have on the stripline PCB dipole antenna. The stripline PCB dipole antenna utilizes a switch mechanism of dual polarized radiation to switch between two of the three radiation planes, namely the XY-plane, the XZ-plane and the YZ-plane. The stripline PCB dipole antenna thus achieves optimum diversity reception efficiency under the control of an external device.Type: GrantFiled: March 5, 2001Date of Patent: January 29, 2002Assignee: Hon Hai Precision Ind.
