An electronic device comprising:

• a main unit chassis having a lower surface and an upper surface, wherein said lower surface of said main unit chassis is covered by a base cover formed of a conductor, wherein said upper surface of said main unit chassis is covered by a keyboard and a keyboard cover formed of a dielectric, wherein said base cover includes a slot;
• a hinge;
• a slot antenna;
• and
• a display chassis having a lower surface and an upper surface, wherein said display chassis is connected to said main unit chassis via said hinge, wherein said upper surface of said display chassis is covered by a display cover formed of a conductor, wherein said lower surface of said display chassis is covered by a display unit and a bezel formed of a dielectric, wherein said slot antenna is located at a bezel area of said display cover, wherein said slot of said base cover is located at a position that opposes a slot of said slot antenna when said display cover of said display chassis is overlapped with said lower surface or said upper surface of said main unit chassis.
