Abstract
An electronic device may be provided with a housing in which electrical components are mounted. The housing may include a metal portion that serves as ground. An antenna for the electronic device may be formed from metal traces on an antenna support such as a flexible printed circuit. The flexible printed circuit may be mounted to a speaker box. The speaker box may have one or more walls formed from metal plates. A metal plate in a speaker box may be coupled to a metal clip. The metal clip may be shorted to a metal stiffener that overlaps a tail portion of the flexible printed circuit. The metal stiffener may have an opening that is aligned with an opening in the metal clip. A metal fastener such as a screw may pass through the openings to short the metal clip, stiffener, and metal plate to ground.
