Electronic device with integrated housing and display antenna

An electronic device 10 comprises: a housing having conductive sidewalls 12W, a conductive turret 12T separated from the conductive sidewalls by a slot 74, and a conductive bridge 12B coupling the conductive turret to the conductive sidewalls across the slot; a display 14 mounted to the conductive turret and having conductive structures 70; and an antenna 40 having a patch element 66 formed from the conductive turret and the conductive display structures, and an antenna ground that includes the conductive sidewalls. The slot may define radiating edges of the radiating element. The display may comprise a conductive ring 78 that forms part of the patch element and couples the display to the conductive turret. A dielectric gasket (86, Figure 6) may be laterally interposed between the conductive display structures and the conductive turret. The electronic device may be a wristwatch, and may comprise a wrist strap 16 attached to the conductive sidewalls. Integrating the antenna into the device in this way may maximize the bandwidth of the antenna by extending the antenna area to include the entire lateral area of the electronic device. This may also serve to maximize the active area of the display.
