Information handling system glass housing having an integrated antenna
A portable information handling system glass ceramic housing integrates plural wires on opposing sides that interface with a radio to provide a dipole antenna, such as with a radio conductor output interfaced at a wire of the interior side and a radio ground output interfaced at a wire of the exterior side. Conductive contacts interface with the wires by exposure at the glass ceramic housing interior where pogo pins of a printed circuit board assembly bias against the conductive contacts to communicate the radio signals. In one example embodiment, the conductive contacts co-locate with a logo etched into the glass ceramic housing to provide an aesthetically pleasing antenna interface that is difficult to visually detect at the glass ceramic housing exterior.
