Patent attributes
A printed dipole antenna used in an electronic device comprising a PCB comprising some through holes; a grounding element locating on one side of the PCB; a radiating element locating on common side of the PCB with the grounding element; a coaxial cable comprising a inner conductor connecting to the radiating element and a braiding layer connecting to the grounding element; and a short circuit element locating on another side of the PCB electrically connecting the radiating element and the grounding element by said through holes. When the printed dipole antenna encounter an intense electromagnetic field, the interferential signal transmitting from the intense electromagnetic field would arrive to the grounding element through the radiating element. The interferential signal cannot arrive to the system and is unable disturb the working of the printed dipole antenna.
