Abstract: An electronic device may have conductive sidewalls and a rear wall. The rear wall may have a first portion mounted to the sidewalls and a second portion protruding away from the first portion to define a cavity. A sensor board may be mounted within the cavity. A coil structure may be mounted within the cavity and surrounding the sensor board. An antenna may have an antenna ground separated from a patch element by an antenna volume. The patch element may include a first conductive trace on the first portion of the rear wall, a second conductive trace on the sensor board, and a conductive interconnect structure that couples the first conductive trace to the second conductive trace. The coil structure may be disposed outside of the antenna to minimize impact of the coil structure on performance of the antenna.

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 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.

Abstract: An electronic device such as a wristwatch may have a housing with metal sidewalls and a display having conductive display structures. The display structures may be separated from the sidewalls by a slot for an antenna that runs around the display module. A conductive interconnect may be coupled between the sidewalls and the display structures. A feed and tuning element may be coupled between the display structures and the sidewalls. A first length of the slot from the interconnect to the tuning element may radiate in a satellite band and a cellular band. A second length of the slot from the interconnect to the feed may radiate in a 2.4 GHz band. Harmonics of the second length may radiate in bands at and above 5.0 GHz. If desired clip and blade structures may form conductive paths for coupling antenna elements.

Abstract: 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.

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.

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.
