Stripline pcb dipole antenna

Abstract

A stripline PCB dipole antenna for use in an electronic device includes a substrate ( ), a first dipole antenna ( ), a second dipole antenna ( ), a first feeder apparatus ( ), and a second feeder apparatus ( ). 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.
