Abstract: A head-mounted device may be worn on a head of a user. While the head-mounted device is being worn, optical modules in the head-mounted device may provide images to eye boxes located rearward of the head-mounted device. A forward-facing display on a front portion of the head-mounted device may be covered with a transparent housing portion forming a display cover layer. An antenna may be mounted in the device. An antenna support member may be coupled to the head-mounted housing. A biasing member such as a layer of foam may have first and second opposing surfaces characterized by surface normals. The foam may be characterized by an axis of preferential compression that is not parallel to the surface normals. The support member may press against the foam so that the antenna presses against an edge portion of the display cover layer or other overlapping dielectric layer.

Abstract: An electronic device may have first and second rear-facing displays, a front-facing display, a cover at a front side overlapping the front-facing display, and an antenna that radiates through the cover. The cover may have a three-dimensional curvature. The device may have an inner chassis and an outer chassis. The antenna may include a radiating element and a ground trace on a flexible printed circuit. To maximize wireless performance of the antenna, the ground trace may be electrically coupled to as much conductive material in the vicinity of the antenna as possible. For example, the ground trace may be grounded to conductive structures in the front-facing display via a conductive cavity for the antenna, may be grounded directly to the outer chassis using conductive screws, and/or may be grounded directly to the inner chassis using conductive screws.

Abstract: A head-mounted device may have a head-mounted housing that is configured to be worn on a head of a user. While the head-mounted device is being worn, optical modules in the head-mounted device may provide images to eye boxes located rearward of the head-mounted device. A forward-facing display on a front portion of the head-mounted device may be covered with a transparent housing portion forming a display cover layer. An antenna may be mounted in the device. A curved portion of the display cover layer or other dielectric housing layer may overlap the antenna. The antenna and/or other components may be formed by contouring a flexible printed circuit into a shape characterized by a surface with compound curvature. The contoured flexible printed circuit may have polymer layers and a metal trace between the polymer layers. A neutral stress plane may be aligned with the metal trace.
