    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 such as a wristwatch device may have a housing with metal sidewalls and a display module having conductive display structures. The conductive display structures may be separated from the sidewalls by a slot element for a first antenna that runs around the display module. A feed element for the first antenna may be coupled between the display structures and the sidewalls. An antenna resonating element for a second antenna may be disposed within the slot element. A printed circuit may include additional antenna elements for the second antenna. The antenna resonating element may extend away from the feed element for the first antenna to provide improved isolation between the two antennas. The first antenna may be operable to provide coverage for frequencies that are lower than frequencies for which the second antenna may be operable to provide coverage.

    Abstract: An electronic device may include a display formed at a front face and a backside circuitry module formed at a rear face that opposes the front face. The backside circuitry module may be surrounded by coil structures and may be aligned with a protrusion in a rear wall housing at the rear face. The backside circuitry module may include a substrate to which sensor components or other components may be mounted. In particular, sensor circuitry, sensors, transceiver circuitry, connector circuitry, etc. may be mounted to the substrate. Antenna structures may be embedded within the substrate along with conductive paths for the sensor components and other components mounted to the substrate. Support structures in the backside circuitry module may support the substrate, sensor components, and other components. If desired, antenna structures may be formed on the support structures.

    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 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 phased antenna array for conveying first signals at a first frequency between 10 GHz and 300 GHz and a non-millimeter wave antenna for conveying second signals at a second frequency below 10 GHz. The device may include conductive housing sidewalls and a display. Conductive structures in the display and the conductive housing sidewalls may define a slot element in the non-millimeter wave antenna. The phased antenna array may be mounted within the slot element, aligned with a spatial filter in the display, or aligned with a dielectric window in the conductive housing sidewalls. Control circuitry may process signals transmitted by the phased antenna array and a reflected version of the transmitted signals that has been received by the phased antenna array to detect a range between the device and an external object.
