Peripheral electronic device housing members with gaps and dielectric coatings

摘要

An electronic device such as a handheld device may have a rectangular housing with a rectangular periphery. A conductive peripheral housing member may run along the rectangular periphery and may surround the rectangular housing. Radio-frequency transceiver circuitry within the electronic device may be coupled to antenna structures for transmitting and receiving radio-frequency signals. The conductive peripheral housing member may form part of the antenna structures. A gap in the conductive peripheral housing member may be filled with dielectric. The conductive peripheral housing member may be configured to form a recess. The recess may have the shape of a rectangle, oval, diamond, or other shape that overlaps and is bisected by the gap. The recess may also have the shape of a groove that extends around the entire periphery of the housing. The dielectric in the recess may include one or more different materials such as clear and opaque polymers.

主权项

1. An electronic device having a periphery, a length, a width, and a height, the electronic device comprising:
at least one antenna that is formed at least partly from a conductive peripheral housing member that runs along the periphery and has an exterior, and interior, and a gap at the exterior; ground structures; a first antenna feed connected to the conductive peripheral housing member; a second antenna feed connected to the ground structures; and a dielectric structure formed on the conductive peripheral housing member that overlaps the gap, wherein the dielectric structure extends parallel to the length and the conductive peripheral housing member has inwardly extending protrusions at the gap that extend from the interior of the conductive peripheral housing member towards an interior of the electronic device.
