Abstract: 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.

Abstract: An electronic device such as a wireless earbud may have antenna structures that are configured to form one or more antenna portions or antennas for transmitting and receiving wireless signals. The device may include control circuitry that is configured to selectively activate one or more antennas or antenna portions to transmit and receive wireless signals for the device. The device may include sensor circuitry that provide sensor data to the control circuitry. The control circuitry may use the sensor data to select and activate an optimal antenna based on the orientation of the earbud or the environment of the device. The antennas may be formed on opposing sides of a housing for the device. By providing configurable antenna structures, the device may be configured to adapt to the current environment and efficiently perform communications operations.

Abstract: An electronic device may have a display cover layer mounted to a metal housing. Electrical component layers such as a display layer, touch sensor layer, and near-field communications antenna layer may be mounted under the display cover layer. An antenna feed may have a positive feed terminal coupled to the electrical component layers and a ground feed terminal coupled to the metal housing. The electrical component layers may serve as an antenna resonating element for an antenna. The antenna may cover cellular telephone bands and may receive satellite navigation system signals. A system-in-package device may be mounted to the metal housing. A flexible printed circuit may extend between the electrical component layers and the system-in-package device. A mounting bracket for the system-in-package device may be provided with electrical isolation to enhance antenna performance in bands such as a satellite navigation system band.

Abstract: An electronic device may be provided with wireless circuitry that includes antenna structures used to determine the position and orientation of the electronic device relative to external wireless equipment. The electronic device may include a housing having a planar conductive layer, a first slot antenna that includes a first bent slot element in the planar conductive layer, and a second slot antenna that includes a second bent slot element in the planar conductive layer. The first and second bent slot elements may be configured to receive radio-frequency signals at the same frequency. The first and second bent slot elements may have the same shape. The electronic device may include control circuitry configured to measure a phase difference between the radio-frequency signals received by the first and second slot antennas. The control circuitry may identify an angle of arrival of the received radio-frequency signals based on the measured phase difference.

Abstract: 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.

Abstract: An electronic device may have a housing and other structures that form an antenna ground for an antenna. An antenna resonating element arm for the antenna may extend along the periphery of the housing. The resonating element arm may have opposing first and second ends. A return path may couple the resonating element arm to the antenna ground at the first end. An antenna feed may be coupled between the resonating element arm and the antenna ground in parallel with the return path. Electrical components such as first and second capacitors may be coupled between the antenna resonating element arm and the antenna ground. A first of the capacitors may be coupled between the antenna resonating element arm and the antenna ground at a location between the first and second ends. A second of the capacitors may be coupled between the second end and the antenna ground.

Abstract: An electronic device may include first and second antennas and a Bluetooth transceiver. Control circuitry may perform Bluetooth antenna diversity operations by coupling the Bluetooth transceiver to a selected one of the first and second antennas at a given time. The Bluetooth transceiver may transmit a first Bluetooth data packet and may determine whether a scheduled response packet associated with the first packet has been received over the first antenna during a predetermined time period. In response to determining that the Bluetooth transceiver has failed to receive the scheduled response packet during the first predetermined time period, the Bluetooth transceiver may re-transmit the first packet using the second antenna. This may serve to reduce the error rate of the transmitted Bluetooth data over time relative to scenarios where a single antenna is used, without requiring resource-intensive sensor circuitry to actively monitor the performance of the antennas.

Abstract: An accessory such as a wireless earbud may have an antenna for transmitting and receiving wireless signals. A housing for the earbud may have a main body portion and an extended portion that forms a stalk protruding from the main body portion. The earbud may have a speaker aligned with a speaker port in the main body portion. The antenna may have an elongated shape and may extend along the stalk. The stalk may have a plastic housing wall portion. The antenna may be formed from first and second metal traces on opposing sides of a printed circuit substrate. The first metal trace may form an antenna resonating element arm and may lie between the substrate and the plastic housing wall portion. The second metal trace may be a ground trace. A feed for the antenna may be located at a juncture between the main body portion and the stalk.

Abstract: An electronic device may have components mounted in a housing. The device may include wireless transceiver circuitry and antenna structures. A display may be mounted in the housing. The display may have a cover layer having an inner surface with a recess. The recess may run along a peripheral edge of the cover layer. An antenna structure such as an inverted-F antenna resonating element may be formed from a metal trace on a dielectric antenna carrier. The resonating element may be mounted in the recess without adhesive. Conductive vias may pass through the dielectric carrier. Metal members with dimples may be soldered to a flexible printed circuit and may be used to ground metal traces on the carrier and the flexible printed circuit to the housing when the carrier is attached to the housing with fasteners.
