Abstract: An electronic device such as a wristwatch may include a housing with a dielectric rear wall. Wireless circuitry in the device may include an antenna formed on or over the rear wall. Matching circuitry may match the impedance of the antenna to the rest of the wireless circuitry. Processing circuitry may gather receive signal strength information and/or phase and magnitude information from radio-frequency signals received through the rear wall. The processing circuitry may track the position of the device and accumulate user statistics over time. The processing circuitry may determine whether changes in loading of the antenna through the dielectric rear housing wall have occurred based on the receive signal strength information, user statistics, and/or phase and magnitude information. If a change is detected, the processing circuitry may adjust the matching circuitry to mitigate any potential antenna detuning as a result of the change.

Abstract: An electronic device such as a wristwatch may have a housing with metal sidewalls and a dielectric rear wall. The metal sidewalls may form an antenna ground for an antenna. The antenna may include an antenna resonating element formed from conductive traces patterned directly onto an interior surface of the dielectric rear wall. The conductive traces may define a slot at the dielectric rear wall. A coil and a sensor may be mounted to the dielectric rear wall within the slot. Radio-frequency transceiver circuitry may be coupled to the conductive traces and the antenna ground and may transmit and receive radio-frequency signals through the dielectric rear wall using the antenna. Wireless power receiver circuitry may use the coil to receive wireless power signals through the dielectric rear wall. The sensor may emit and/or receive light through a transparent window in the dielectric rear wall.

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 be provided with wireless circuitry and a housing having peripheral conductive housing structures. The wireless circuitry may include first and second antennas. The first antenna may have a resonating element arm formed from a first segment of the peripheral conductive housing structures. The second antenna may have a resonating element arm formed from a second segment of the peripheral conductive housing structures separated from the first segment by a gap. Switchable short paths may be coupled between the second segment and ground on opposing sides of an antenna feed for the second antenna and/or may be coupled between the first and second segments and ground on opposing sides of the gap. Additionally or alternatively, a switch may be coupled between the first and second segments across the gap and a tuning component may couple the second segment to the ground structures.

Abstract: An electronic device may be provided with wireless circuitry that includes first, second, and third antennas used to determine the position and orientation of the electronic device relative to external equipment. The antennas may include patch elements on respective substrates mounted to a flexible printed circuit. Each substrate may include fences of conductive vias that are coupled to ground and that laterally surround the corresponding patch element. Control circuitry may identify phase differences between the first and second antennas and between the second and third antennas and may identify an angle of arrival of received ultra-wideband signals using the phase differences. The control circuitry may compare the phase differences to a set of predetermined surfaces of phase differences to identify environmental loading conditions for the antenna. The control circuitry may correct the angle of arrival using offsets identified based on the environmental loading conditions.

Abstract: An electronic device may include an antenna disposed on a substrate. The antenna may include a ring of conductive traces, a fed arm, and an unfed arm. The fed arm and the unfed arm may extend from opposing segments of the ring. The ring may be coupled to ground by fences of conductive vias extending through the substrate. The first arm may have a first radiating edge. The second arm may have a second radiating edge. The first radiating edge may be separated from the second radiating edge by a gap. The first arm may indirectly feed the second arm via near-field electromagnetic coupling across the gap. The first and second arms may collectively radiate in an ultra-wideband (UWB) frequency band.

Abstract: An electronic device may be provided with a housing, a logic board, and wireless circuitry on the logic board. The wireless circuitry may include first and second antennas formed from conductive traces on a surface of the logic board. The first and second antennas may include resonating element arms at opposing sides of the logic board. The first antenna may have a fundamental mode that radiates in a Bluetooth® communications band at 2.4 GHz. The second antenna may radiate in a first ultra-wideband communications band such as a 6.5 GHz ultra-wideband communications band. If desired, the second antenna may also radiate in a second ultra-wideband communications band such as an 8.0 GHz ultra-wideband communications band. In another suitable arrangement, a harmonic mode of the first antenna may radiate in the second ultra-wideband communications band.
