Abstract
Cavity antennas may be provided for electronic devices. A cavity antenna may have a conductive antenna cavity with an opening. An antenna resonating element may be soldered within the cavity opening. An electronic device may have a display that is covered by a display cover layer. A cavity antenna may be mounted so that the cavity opening is located under a portion of the display cover layer outside of the active display region. An antenna cavity for a cavity antenna may have one or more bends. A curved antenna cavity or a cavity antenna with one or more angled branches may have a portion that extends between a conductive housing wall and internal device components such as a display. A speaker may be formed using the interior volume within a cavity antenna.
