Abstract: An electronic device may include a rear housing wall, antenna resonating element, sensor board, and grounding ring. The grounding ring may couple antenna currents from the resonating element onto a ground trace on the sensor board. A switchable inductor may couple the grounding ring to the ground traces. The switchable inductor may be used to tune a frequency response of the antenna in a cellular low band. Additionally or alternatively, an inductor may couple the resonating element to the ground traces or other portions of an antenna ground. This inductor may serve to extend the effective length of the antenna resonating element in the cellular low band to compensate for dielectric loading by the rear housing wall, such as in examples where the rear housing wall is formed from zirconia.

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 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, the tuning element may be omitted, and the antenna may be coupled to separate low band and high band matching circuits.

Abstract: An electronic device such as a wristwatch may be provided with a wireless local area network (WLAN) transceiver, satellite receiver, and cellular transceiver. A first antenna may include a radiating slot between a conductive housing wall and a display module. A second antenna may include conductive structures that radiate through a rear face of the device. The WLAN transceiver and the satellite receiver may be coupled to the first antenna. A switch may be coupled between the cellular transceiver and the first and second antennas. Control circuitry may adjust the switch to route signals between the cellular transceiver and a selected one of the first and second antennas based on wireless performance metric data so that the antenna exhibiting superior wireless performance at cellular telephone frequencies is used for cellular telephone communications regardless of environmental conditions.

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 may have conductive sidewalls, a conductive turret, and a conductive bridge. The turret may be separated from the sidewalls by a slot. A display may be mounted to the turret and may include conductive display structures and a conductive ring that couples the display to the turret. An antenna in the device may have a radiating element formed from the conductive display structures, the ring, and the turret. The conductive bridge may form a short path across the slot to the sidewalls. The slot may define radiating edges of the radiating element. Integrating the antenna into the device in this way may maximize the bandwidth of the antenna by extending the antenna area to include the entire lateral area of the electronic device. This may also serve to maximize the active area of the display.
