15. An information handling system to transmit a communication signal comprising:
a display housing containing components of the information handling system including a processor, a memory, and a power management unit, the display housing including a back metal chassis;
a selectively detachable metal keyboard chassis operatively couplable via a hinge;
a plurality of sidewalls formed along the edges of a back side of the display housing and generally perpendicular to the back side;
a ring of two or more antennas formed into two or more sidewalls of the display housing nested in plastic molding surrounding each of the two or more antennas and isolating the two or more antennas from the back metal chassis and metal portions of the plurality of sidewalls, and where the ring of two or more antennas formed into two or more sidewalls of the display housing nested in plastic molding are configured to, via a wireless interface adapter, create radiating radio frequency (RF) bands for wireless communications;
a feed excitation trace to transmit an excitation current to the antenna from the wireless interface adapter;
a coupling arm to form a capacitive coupling with the antenna;
the plastic molding in the sidewall to secure the antenna near the coupling arm and to the sidewall but isolate the antenna from the metal portion of the sidewall; and
a thermal vent formed at the two or more antennas to vent from the interior of the display housing.
