System and method for an isolator for a hinge cavity of an information handling system having one or more antenna elements

A metal base chassis and metal display chassis assembly for an information handling system comprising:

• a processor;
• a memory;
• a wireless adapter operatively coupled to a first antenna and a second antenna to wirelessly transceiver data;
• a hinge cavity formed between the metal base chassis and the metal display chassis, the base metal chassis including a C-cover and D-cover and the display metal chassis including an A-cover and a B-cover;
• the first antenna formed within the C-cover by the hinge cavity;
• the second antenna formed within the C-cover by the hinge cavity;
• and
• an edge resonant isolator formed into an edge of the A-cover adjacent to the hinge cavity to disrupt an electrical ground coupling path formed between the metal base chassis and metal display chassis at the hinge cavity, wherein the edge resonant isolator has a plurality of slits formed into the A-cover from the edge and sized to isolate the first antenna and the second antenna along the hinge cavity.

An information handling system to transmit a communication signal comprising:

• a metal base chassis containing components of the information handling system including a processor, a memory, and a wireless adapter, the base metal chassis including a C-cover and D-cover housing the components;
• a metal display chassis containing components of the information handling system, the display metal chassis including an A-cover and a B-cover;
• a hinge cavity formed at a hinge used to couple the metal base chassis and metal display chassis;
• a first antenna element formed within the C-cover by the hinge cavity;
• a second antenna element formed within the C-cover by the hinge cavity;
• a metal pronged edge resonant isolator formed into an edge of the A-cover to disrupt an electrical ground coupling path formed between the base metal chassis and display metal chassis at the hinge cavity, wherein the metal pronged edge resonant isolator includes a plurality of slits formed into the A-cover among prongs of the metal pronged edge isolator;
• the plurality of slits comprising a first set of narrow slits and a second set or relatively wider slits to decouple high band frequencies from lower-band frequencies respectively.
