Abstract

According to an aspect, a display device includes a display module including a display panel and a conductive layer, and an enclosure configured to surround the display module, where the enclosure includes a conductive portion. The display device includes an antenna having a structure formed by an air gap disposed between the conductive layer and the conductive portion of the enclosure. The antenna includes an antenna feed located within the air gap. The antenna feed is coupled to the conductive portion of the enclosure and to the conductive layer such that at least a portion of the display module is configured as a radiating element for wireless communication.
