Embodiment Construction

[0019] An electronic device may be provided with conductive structures for forming one or more antennas. The conductive structure may include a conductive housing structure. An electronic device may include a display having a display module overlying a display cover. The display module may include conductive display structures. Adhesives may be used to secure the display cover to the conductive housing structure.

[0020] Conductive display structures can occupy a significant portion of the lateral area of ​​the display in order to provide the largest possible active area for the display. This can limit the volume within the electronic device that can be used to form the antenna. Limiting antenna volume in this manner can limit antenna bandwidth and efficiency if care is not taken. Similarly, conductive display structures can prevent the antenna from radiating through the display cover with satisfactory bandwidth and efficiency.

[0021] To maximize the bandwidth and effi...

Abstract

The invention relates to a display grounding structure. An electronic device may be provided with a display and conductive sidewalls. The display may include conductive display structures and a coverlayer. The cover layer may be mounted to the sidewalls. The sidewalls may define antenna apertures for antennas in the device. Grounding structures may be coupled between the conductive display structures and the sidewalls at locations that at least partially overlap the antenna apertures. The grounding structures may include conductive tape having an adhesive surface. The conductive tape may havea first end at which the adhesive surface is coupled to the conductive display structures. The conductive tape may have a second end that is folded around a layer of heat-activated film and that is coupled to both the display cover layer and the conductive sidewalls. Conductive tape overlapping each antenna aperture may be concurrently assembled into the electronic device as the display is mounted to the sidewalls.

Description

[0001] This patent application claims priority to U.S. Patent Application No. 16 / 134,738, filed September 18, 2018, which is hereby incorporated by reference in its entirety. technical field [0002] The present invention relates generally to electronic devices, and more particularly to electronic devices having wireless circuitry. Background technique [0003] Electronic devices often include wireless circuitry with antennas. For example, cellular telephones, computers and other devices often contain antennas to support wireless communications. [0004] Forming electronic device antenna structures with desired properties can be challenging. In some wireless devices, the presence of conductive structures, such as conductive housing structures and conductive components, can affect antenna performance. Antenna performance may be unsatisfactory if the conductive structures are not properly configured and interfere with antenna operation, or if the antenna is adversely affecte...
