Electronic Device with Integrated Housing and Display Antenna

An electronic device may have conductive sidewalls, a conductive turret, and a conductive bridge. The turret may be separated from the sidewalls by a slot. A display may be mounted to the turret and may include conductive display structures and a conductive ring that couples the display to the turret. An antenna in the device may have a radiating element formed from the conductive display structures, the ring, and the turret. The conductive bridge may form a short path across the slot to the sidewalls. The slot may define radiating edges of the radiating element. 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.
