Antenna solution for narrow bezel system
Systems and methods are disclosed for positioning an antenna in a portable information handling system. A portable information handling system includes a housing having a first housing portion and a second housing portion. The portable information handling system also includes a hinge assembly rotationally coupling the first and second housing portions. The portable information handling system also includes an antenna disposed within the first housing portion, the antenna operable to transmit radio waves. The portable information handling system further includes an antenna aperture formed within the first housing portion. The second housing portion comprises a radio frequency (RF) permeable region comprising RF permeable material, the RF permeable region located in proximity to the antenna aperture when the portable information handling system is in tablet mode, tablet mode representing the first housing portion rotated approximately 360 degrees from the second housing portion.

an antenna disposed within the first housing portion, the antenna operable to transmit radio waves; and
an antenna aperture formed within the first housing portion such that at least a portion of the radio waves transmitted from the antenna travel through the antenna aperture;
the second housing portion comprising a radio frequency (RF) permeable region comprising RF permeable material, the RF permeable region located in proximity to the antenna aperture when the portable information handling system is in tablet mode, tablet mode representing the first housing portion rotated approximately 360 degrees from the second housing portion;
wherein the second housing portion comprises an interference free zone located in proximity to the antenna when the portable information handling system is in tablet mode such that at least a portion of the radio waves transmitted from the antenna travel through the interference free zone, the interference free zone comprising RF permeable components.
2. The system of claim 1 , wherein RF permeable material covers the antenna aperture.
3. The system of claim 1 , wherein an edge the first housing portion overhangs an edge of the second housing portion when the portable information handling system is in tablet mode.
4. The system of claim 1 , wherein the first housing portion comprises an electrically conductive portion and a low-electrically conductive portion, wherein the low-electrically conductive portion is located at an edge of the first housing portion to dissipate a surface current created by the radio waves from the antenna.
5. The system of claim 4 , wherein the electrically conductive portion comprises slits to dissipate the surface current created by the radio waves from the antenna.
6. The system of claim 5 , wherein the low-electrically conductive portion covers the slits in the electrically conductive portion.
7. The system of claim 1 , wherein the interference free zone comprises walls disposed within in the second housing portion, the walls forming an empty space within the second housing portion.
8. The system of claim 1 , wherein the interference free zone comprises RF permeable material disposed within in the second housing portion.
9. A method of integrating an antenna in a portable information handling system, comprising:
rotationally coupling a first housing portion and a second housing portion of the portable information handling system with a hinge assembly;
placing the antenna within the first housing portion, the antenna operable to transmit radio waves;
forming an antenna aperture within the first housing portion such that at least a portion of the radio waves travel through the antenna aperture; and
placing a radio frequency (RF) permeable region comprising RF permeable material within the second housing portion, the RF permeable region located in proximity to the antenna aperture when the portable information handling system is in tablet mode, tablet mode representing the first housing portion rotated approximately 360 degrees from the second housing portion;
