Electronic displays and electronic devices including such electronic displays and antennas are provided for improved transmission of signals through circuitry of the electronic display. The electronic display may include multiple power supply tiles that are separated with non-conductive gaps to reduce circulation of eddy currents induced by the transmission signals. Moreover, voltage supply routing paths within the power supply tiles may be grouped to provide non-conductive gaps within the power supply tiles. Accordingly, the antenna may provide the transmission signals through the electronic display with improved efficiency based on reducing surface currents (e.g., eddy currents) on the electronic display.

Display and antenna co-design to reduce antenna transmission loss

A portable or wearable electronic device can include a device housing defining an internal volume, and an electronic component disposed in the internal volume. The electronic component can be an input component and can have a component housing. The electronic device can also include an antenna feed assembly disposed in the internal volume. The antenna feed assembly can include a conductive grounding component electrically connected to the component housing and the device housing, and an antenna feed component electrically connected to the grounding component and disposed adjacent to the component housing. The conductive grounding component can surround a first major surface and a second major surface of the component housing.

Electronic device

An electronic device such as a wristwatch device may have a housing with metal sidewalls and a display module having conductive display structures. The conductive display structures may be separated from the sidewalls by a slot element for a first antenna that runs around the display module. A feed element for the first antenna may be coupled between the display structures and the sidewalls. An antenna resonating element for a second antenna may be disposed within the slot element. A printed circuit may include additional antenna elements for the second antenna. The antenna resonating element may extend away from the feed element for the first antenna to provide improved isolation between the two antennas. The first antenna may be operable to provide coverage for frequencies that are lower than frequencies for which the second antenna may be operable to provide coverage.

Electronic device wide band antennas

An electronic device such as a wristwatch may be provided with a phased antenna array for conveying first signals at a first frequency between 10 GHz and 300 GHz and a non-millimeter wave antenna for conveying second signals at a second frequency below 10 GHz. The device may include conductive housing sidewalls and a display. Conductive structures in the display and the conductive housing sidewalls may define a slot element in the non-millimeter wave antenna. The phased antenna array may be mounted within the slot element, aligned with a spatial filter in the display, or aligned with a dielectric window in the conductive housing sidewalls. Control circuitry may process signals transmitted by the phased antenna array and a reflected version of the transmitted signals that has been received by the phased antenna array to detect a range between the device and an external object.

Electronic devices having millimeter wave ranging capabilities

An electronic device housing may be formed from housing members. A first housing member may form a display cover layer that overlaps pixels. During operation, the pixels may display an image that is viewable through the display cover layer. The second housing member may have a rear wall portion and a sidewall. A band may be coupled to the sidewall or other portion of the second housing member. The first and second housing members may be attached together using a housing member attachment structure. The housing member attachment structure may have layers of adhesive and printed circuit structures. The printed circuit structures may include metal traces that form an antenna and that form capacitive force sensor electrodes on opposing sides of a compressible member.

Electronic devices having circuitry in housing attachment structures

An electronic device such as a wristwatch may have a housing with metal portions such as metal sidewalls. The housing may form an antenna ground for an antenna. An antenna resonating element for the antenna may be formed from a stack of capacitively coupled component layers such as a display layer, touch sensor layer, and near-field communications antenna layer at a front face of the device. An additional antenna may be formed from a peripheral resonating element that runs along a peripheral edge of the device and the antenna ground. A rear face antenna may be formed using a wireless power receiving coil as a radio-frequency antenna resonating element or may be formed from metal antenna traces on a plastic support for light-based components.

Electronic device antennas

An electronic device may include a rear housing wall, antenna resonating element, coil, sensor board, and antenna grounding ring structures. The coil may receive wireless charging signals through the grounding ring structures and the rear housing wall. The grounding ring structures may include concentric ring-shaped traces. The ring-shaped traces may be separated by at least one gap. The ring-shaped traces and the gaps may configure the grounding ring structures to short antenna currents at relatively high frequencies from the antenna resonating element to a ground trace on the sensor board while blocking currents at relatively low frequencies. This may allow the ground trace to form part of an antenna without substantially impairing wireless charging efficiency of the coil.

Electronic devices having antenna grounding rings

Aspects of the subject technology relate to electronic devices with antennas. The antenna may be a display-integrated antenna. An antenna feed for the antenna may be located in a recess in a sidewall of a housing of the device. The antenna feed may be coupled to transceiver circuitry on a logic board of the device by a pair of flex circuits. A first one of the pair of flex circuits may form a portion of an antenna feed assembly. A second one of the pair of flex circuits may be an impedance-matching flex having an end that is soldered to the main logic board. The antenna may be coupled to a conductive portion of the housing of the device.

Integrated antennas for portable electronic devices

An electronic device may have a housing with metal sidewalls. One of the metal sidewalls may have an opening. The electronic device may have a speaker module that has a speaker housing member. Conductive structures on the speaker housing member may have an opening that forms a slot element. The opening of the metal sidewall may be aligned with slot element. The slot element and an interior cavity of the speaker housing member may form a cavity-backed slot antenna. An antenna feed structure may be disposed at the opening of the speaker housing member. An antenna feed may be directly coupled to the antenna feed structure. The antenna feed structure may indirectly feed the slot antenna resonating element by capacitive coupling. A sealing member may be disposed at the opening of the metal sidewall.

An electronic device such as a wristwatch may have a housing with metal sidewalls and a display having conductive display structures. Printed circuits having corresponding ground traces may be coupled to the display for conveying data to and/or from the display. The conductive display structures may be separated from the metal sidewalls by a gap. A conductive interconnect may be coupled to the metal sidewalls and may extend across the gap to the conductive display structures. The conductive interconnect may be coupled to the ground traces on the printed circuits and/or may be shorted or capacitively coupled to the conductive display structures. When configured in this way, the metal sidewalls, the conductive display structures, and the conductive interconnect may define the edges of a slot antenna resonating element for a slot antenna.

Electronic device slot antennas

An electronic device may include an antenna element, coil, sensor board, and grounding ring structures. The coil may receive wireless charging signals through the grounding ring structures. The grounding ring structures may include concentric ring-shaped traces separated by at least one gap. The ring-shaped traces and gaps may configure the grounding ring structures to short antenna currents at relatively high frequencies from the antenna element to a ground trace on the sensor board while blocking currents at relatively low frequencies. The grounding ring structures may include conductive wings that increase capacitive coupling between the grounding ring structures and the antenna element. The grounding ring structures may be soldered to the antenna element. The antenna element and the grounding ring structures may be formed from traces patterned on the same substrate. The ground trace may form part of an antenna without substantially impairing wireless charging efficiency of the coil.

Electronic devices having extended antenna grounding rings

An electronic device may have peripheral conductive structures and a conductive layer that define edges of a slot element for a slot antenna. The slot element may be configured to cover wireless communications in a 1575 MHz satellite navigation band and 2.4 GHz and 5 GHz wireless local area network bands. A tuning circuit may be coupled across the slot approximately half way across the length of the slot. The antenna tuning circuit may include an inductor coupled in series with a notch filter (in scenarios where the slot is long enough to cover the 1575 MHz satellite navigation band in its fundamental mode) or may include a capacitor coupled in series with a notch or low pass filter. The fundamental mode and one or more harmonic modes of the slot element may cover the satellite navigation and wireless local area network bands.
