Abstract: An electronic device such as a head-mounted display device may include an antenna that radiates through a cover. The antenna may have an antenna resonating element layered onto the cover and having a three-dimensional curvature. The antenna resonating element may have an antenna ground. A pressure-activated connector may electrically couple the antenna resonating element to the antenna ground. If desired, the pressure-activated connector may lock the antenna resonating element to the antenna ground. The pressure-activated connector may include a metal finger, a metal spring, a metal ball, a curling metal receptacle, a dimple, a metal screw, a screw receptacle, metal burs, and/or rotational locking structures. The pressure-activated connector may form a robust mechanical connection between the first and second conductors despite the curvature of the antenna resonating element, which minimizes electrical discontinuities that can otherwise deteriorate antenna performance.

Abstract: A head-mounted device may have a housing with a cover having three-dimensional curvature. A front-facing display may be mounted to the cover and may display images through the cover. The cover may have a peripheral region laterally surrounding the front-facing display. An antenna may have an antenna resonating element layered onto the cover overlapping the peripheral region. The antenna may be switchable between different radiation patterns. A controller may gather wireless performance metric data for each of the radiation patterns. The antenna may be switched to exhibit a radiation pattern that optimizes the wireless performance metric data. This may serve to minimize interference from external devices operating using the same ultra-low-latency audio communications protocol as the antenna.

Abstract: An electronic device such as a head-mounted display device may include an antenna that radiates through a cover. The antenna may have a ground and an antenna resonating element layered onto the cover. The ground may include conductive structures separated from the resonating element by a volume. The device may include a fan that conveys air through a vent in a chassis of the electronic device through a tunnel. The tunnel may be free from conductive material and may extend through the volume of the antenna. The fan may include blades enclosed within metal walls. A conductive mesh may be coupled between the metal walls and may separate the blades from the tunnel. This may serve to extend the volume of the antenna to also include at least some of the volume of the fan, thereby maximizing efficiency bandwidth of the antenna without sacrificing thermal dissipation by the fan.

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: 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 antenna may be formed from traces on a flexible printed circuit. The antenna may be provided with a conductive shield on a dielectric carrier. The flexible printed circuit may be mounted to the carrier opposite the shield. A biasing member may be mounted to the carrier and may press the flexible printed circuit against the cover. To minimize weight of the device, the shield may be formed from conductive traces patterned onto the carrier. The carrier may include first and second substrates formed from respective shots of co-molded plastic. The second substrate may include plateable grade plastic and the conductive traces may be patterned onto plateable outer surfaces of the second substrate opposite the first substrate.

Abstract: An electronic device may have first and second rear-facing displays, a front-facing display, a cover layer at a front side with a central region overlapping the front-facing display and a peripheral region, and wireless circuitry with a transceiver and antennas. The transceiver may convey audio data with left and right earbuds using a non-Bluetooth low-latency-audio communications protocol. The antenna(s) may be mounted at a bottom side of the device overlapping the peripheral region, at a rear side of the device, or may be mounted to a head strap. The antenna(s) may be tilted to optimize field(s) of view, to match polarization of the earbuds, and/or to allow multiple antennas to exhibit orthogonal polarizations. The antennas may include a single antenna that concurrently conveys packets of audio data to both earbuds or may include first and second antennas that concurrently convey audio data to the left and right earbuds.

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 antenna may be formed from sheet metal. The antenna may have a resonating element formed from a first portion of the sheet metal and an antenna ground that includes a second portion of the sheet metal separated from the first portion by a cavity. A third portion of the sheet metal may couple the first portion to the second portion and may be folded around the cavity to produce a spring force that presses the first portion against the cover. The first portion and the cover may have the same compound curvature. The second portion may form a conductive cavity for the antenna.

Abstract: A head-mounted device may have a housing with a cover having three-dimensional curvature. A front-facing display may be mounted to the cover and may display images through the cover. The cover may have a peripheral region laterally surrounding the front-facing display. An antenna may have an antenna resonating element layered onto the cover overlapping the peripheral region. The antenna may be switchable between a first polarization state and a second polarization state. In the first polarization state, the antenna conveys radio-frequency signals having a first polarization with an earbud. In the second polarization state, the antenna conveys radio-frequency signals having a second polarization with the earbud. One or more processors may gather wireless performance metric data from the radio-frequency signals and may adjust the antenna between the polarization states to optimize the wireless performance metric data.
