Electronic devices with antennas and optical components
A head-mounted device may have a head-mounted housing. The housing may include a frame with left and right openings that receive respective left and right optical modules that present images to a user's eyes. Each optical module may have a lens and display that presents an image through the lens. Camera support members may be coupled to respective left and right peripheral portions of the frame. Each camera support member may have openings configured to receive cameras. Antennas may be formed on a camera support member. The antennas may have metal traces on a surface of the camera support member, may have conductive structures embedded within the camera support member, and/or may have patterned metal traces on printed circuits attached to or embedded in the camera support member. The cameras may operate through portions of a display cover layer that covers an outwardly-facing display on the head-mounted housing.
