Abstract
A PCB dipole antenna ( ) for placing in an electronic device includes a first dipole antenna element ( ), a second dipole antenna element ( ), a printed circuit board ( ), a first feeder apparatus ( ) and a second feeder apparatus ( ). The first dipole antenna element is perpendicular to the second dipole antenna element. Each first and second dipole antenna element includes two dipole cells respectively disposed on opposite surfaces of the printed circuit board. Each first and second dipole antenna element is fed through the first and second feeder apparatuses respectively. Switching of dual polarized radiation of the PCB dipole antenna is carried out under the control of an external device. This makes full use of two of the three radiation planes, and provides maximum diversity radiation efficiency.
