Examples are disclosed related to optically transparent antennas. One example provides a proximity sensor, comprising an electrically insulating substrate that is at least partially optically transparent, one or more antennas disposed on the electrically insulating substrate, each antenna comprising a film of a conductive material that is at least partially optically transparent, the one or more antennas comprising a proximity sensing antenna, and a resonant LC circuit electrically coupled to the proximity sensing antenna, the resonant LC circuit configured to output a signal responsive to a position of a surface relative to the proximity sensing antenna.

Optically transparent antennas on transparent substrates

An electronic device may be provided with wireless circuitry. The wireless circuitry may include one or more antennas. The antennas may include phased antenna arrays each of which includes multiple antenna elements. Phased antenna arrays may be mounted along edges of a housing for the electronic device, behind a dielectric window such as a dielectric logo window in the housing, in alignment with dielectric housing portions at corners of the housing, or elsewhere in the electronic device. A phased antenna array may include arrays of patch antenna elements on dielectric layers separated by a ground layer. A baseband processor may distribute wireless signals to the phased antenna arrays at intermediate frequencies over intermediate frequency signal paths. Transceiver circuits at the phased antenna arrays may include upconverters and downconverters coupled to the intermediate frequency signal paths.

Electronic device with millimeter wave antennas

An electronic device may have a display. A display cover layer and a transparent inner display member may overlap a display pixel layer. The display pixel layer may have an array of display pixels for displaying images for a user. A touch sensor layer may be interposed between the display pixel layer and the transparent display member. A ferromagnetic shielding layer may be mounted below the display pixel layer. A flexible printed circuit containing coils of metal signal lines that form a near-field communications loop antenna may be interposed between the ferromagnetic shielding layer and the display pixel layer. A non-near-field antenna such as an inverted-F antenna may have a resonating element mounted on an inner surface of the display cover layer. The resonating element may be interposed between the transparent display member and the display cover layer.

Electronic device with near-field antenna operating through display

An extended reality headset has light-based communication transceivers coupled to the extended reality headset. The relative position of a remote transceiver with respect to the current position and orientation of the extended reality headset is determined. A line-of-sight is calculated from the light-based communication transceivers to the remote transceiver. The light-based communication transceivers emit a light-based communications beam in accordance with the calculated line-of-sight. The light-based communications beam is adjusted in response to changes to the relative position of the remote transceiver with respect to the current position and orientation of the extended reality headset.

Optical over-the-air peer to peer communication for XR devices

Examples are disclosed related to optically transparent antennas. One example provides a device, comprising an electrically insulating substrate that is at least partially optically transparent, one or more antennas disposed on the electrically insulating substrate, each antenna comprising a film of a conductive material that is at least partially optically transparent, the one or more antennas comprising a communication antenna, and processing circuitry electrically coupled to the communication antenna, the processing circuitry configured to one or more of send or receive signals via the communication antenna.

A head-mounted device (HMD) has a segmented metal chassis including a plurality of physically separate radio frequency (RF) antennas corresponding to different head regions. The HMD further includes a plurality of RF transceivers, each electrically connected to a corresponding RF antenna. Each RF transceiver is configured to drive the corresponding RF antenna with a drive signal at a frequency within a resonant frequency band of the corresponding RF antenna and sense a frequency response to the drive signal. The HMD further includes a plurality of notch filter circuits, each electrically connected in series with a corresponding RF antenna. Each notch filter is configured to attenuate signals at frequencies within the resonant frequency band of the corresponding RF antenna and pass signals at frequencies outside of the resonant frequency band, such that the segmented metal chassis functions as a common ground plane.

Head mounted device with segmented chassis

An electronic device may be provided with wireless circuitry. The wireless circuitry may include one or more antennas. The antennas may include millimeter wave antenna arrays. Non-millimeter-wave antennas such as cellular telephone antennas may have conductive structures separated by a dielectric gap. In a device with a metal housing, a plastic-filled slot may form the dielectric gap. The conductive structures may be slot antenna structures, inverted-F antenna structures such as an inverted-F antenna resonating element and a ground, or other antenna structures. The plastic-filled slot may serve as a millimeter wave antenna window. A millimeter wave antenna array may be mounted in alignment with the millimeter wave antenna window to transmit and receive signals through the window. Millimeter wave antenna windows may also be formed from air-filled openings in a metal housing such as audio port openings.

Electronic devices with millimeter wave antennas and metal housings

This invention is directed to an electronic device with an embedded authentication system for restricting access to device resources. The authentication system may include one or more sensors operative to detect biometric information of a user. The sensors may be positioned in the device such that the sensors may detect appropriate biometric information as the user operates the device, without requiring the user to perform a step for providing the biometric information (e.g., embedding a fingerprint sensor in an input mechanism instead of providing a fingerprint sensor in a separate part of the device housing). In some embodiments, the authentication system may be operative to detect a visual or temporal pattern of inputs to authenticate a user. In response to authenticating, a user may access restricted files, applications (e.g., applications purchased by the user), or settings (e.g., application settings such as contacts or saved game profile).

Embedded authentication systems in an electronic device

An electronic device may include control circuitry, sensors, and wireless circuitry having antennas. The sensors may generate sensor data that is used by the control circuitry to identify an operating environment for the device. The sensor data may include a grip map generated by a touch-sensitive display, infrared facial recognition image signals or other image signals, an angle of arrival of sound received by a set of microphones, impedance data from an impedance sensor, and any other desired sensor data. The control circuitry may use the sensor data, radio-frequency spatial ranging data, information about whether audio is being played over an ear speaker, and/or information about communications protocols in use to identify the operating environment. The control circuitry may adjust antenna settings for the wireless circuitry based on the identified operating environment to ensure that the antennas operate with satisfactory antenna efficiency regardless of operating conditions.

Electronic device having adjustable antenna settings

An electronic device having at least one operational setting, such as a power setting, with at least a first state and a second state. The electronic device may also include an access controller that can receive state data and authorization data from an external source such as a remote control. The access controller may enable a state of the operational setting upon receipt of proper authorization data received from or related to the output from at least one biometric sensor associated with the remote control.

Electronic device operation using remote user biometrics

Systems and method for improving performance of a radio frequency system are provided. One embodiment describes a radio frequency system, which may be modified based upon a detected housing and/or accessory of an electronic device. The modifications may counteract impacts of the housings and/or accessories on the radio frequency transmission.
