Electronic devices having housing-integrated antennas

An electronic device, comprising:

• a display having a display cover layer and a display panel configured to emit light through the display cover layer;
• a housing having a conductive wall and peripheral conductive structures that extend around a periphery of the electronic device and from the conductive wall to the display cover layer;
• a dielectric substrate interposed between the display cover layer and the conductive wall, wherein first and second portions of the peripheral conductive structures define edges of a slot element in a slot antenna at a surface of the dielectric substrate and the second portion of the peripheral conductive structures is formed on the surface of the dielectric substrate;
• and
• a conductive layer on an additional surface of the dielectric substrate that shorts the second portion of the peripheral conductive structures to the conductive wall.

An electronic device comprising:

• a housing having a conductive rear wall and peripheral conductive housing structures with an integral ledge portion;
• a display having a display cover layer mounted to the integral ledge portion and a display module configured to emit light through the display cover layer, wherein the integral ledge portion runs around at least some of a periphery of the display module;
• and
• a cavity-backed antenna having a radiating element that is formed from the integral ledge portion and that is backed by a conductive cavity defined by the conductive rear wall, the peripheral conductive housing structures, a conductive layer coupled between the radiating element and the conductive rear wall, and a conductive patch in the slot, wherein the conductive patch is configured to indirectly feed the cavity backed antenna.
