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.

The present invention provides an integrated antenna and visual display apparatus, or one of an antenna apparatus and visual display apparatus which is integratable with the other. Apertures are formed in a visual display, such as an OLED display. The apertures when formed in a conductive layer operate as radiating bodies of an antenna array. A subset of sub-pixels of the visual display can be removed in line with the apertures. An optically transparent substrate is located over the visual display, and an array of further conductive elements, which may be optically transparent, is disposed on an exterior of this substrate. The further conductive elements operate to direct the antenna signals through the substrate, by coupling in an impedance-matched manner with the radiating apertures.

An electronic device may have an upper housing and a lower housing separated by a slow. A substrate may be mounted in the lower housing and may have an inner surface facing an interior of the lower housing and an outer surface facing the slot. Ventilation port openings may extend from the outer surface to the inner surface. Ribs in the substrate may separate the ventilation port openings. The ribs may include notches at the inner surface. An antenna may include conductive traces within multiple ventilation port openings and extending through the notches. The conductive traces may be offset from the outer surface. The outer surface of the substrate may be free from conductive material from the antenna. This may serve to maximize antenna efficiency while protecting the antenna from external forces and debris or other contaminants that pass through the slot during use of the electronic device over time.

The invention relates to a protective helmet, comprising an outer shell (1) for distributing impact forces and an antenna (2) for transferring a radio signal, which antenna is arranged at least partially inside the outer shell (1). The outer shell (1) consists of a main material in a main region (5). The protective helmet is characterized in that the outer shell (1) consists of a cut-out material in a cut-out region (6), the cut-out material having a lesser damping effect on the radio signal in comparison with the main material. The invention further relates to a method for producing a protective helmet.
