Abstract: An electronic device may have an upper housing and a lower housing separated by a slot. An antenna module may be mounted in the lower housing and may include a cavity. An antenna element may be disposed within the cavity. Grounded traces may be patterned onto walls of the module and may be coupled to conductive walls of the lower housing by conductive gaskets. The antenna element may have a high band arm displaced farther into the cavity than a low band arm by a shim. The antenna module may have an acoustic port aligned with a speaker port. The acoustic port may allow sound waves from a speaker to pass into the cavity from the speaker port. The cavity may be configured to optimize an audio response of the speaker while concurrently optimizing radio-frequency performance of the antenna element.

Abstract: An electronic device such as a desktop computer may have a housing with a conductive housing wall and a display mounted to the housing opposite the conductive housing wall. A conductive tongue may extend through an opening in the housing wall to secure the housing to a hinge barrel on a desktop stand. A slot antenna may be formed from a slot element in the conductive tongue. The antenna may be fed by a flexible printed circuit coupled across the slot element or by a feed printed circuit in the housing that is coupled to the conductive tongue by a conductive screw. A conductive sleeve may be placed over the conductive tongue. The stand may be replaced with a mounting bracket.
