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.
