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 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 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.

Abstract: An electronic device may be provided with wireless circuitry. Control circuitry may be used to adjust the wireless circuitry. The wireless circuitry may include an antenna that is tuned using tunable components. The control circuitry may gather information on the current operating mode of the electronic device, sensor data from a proximity sensor, accelerometer, microphone, and other sensors, antenna impedance information for the antenna, and information on the use of connectors in the electronic device. Based on this gathered data, the control circuitry can adjust the tunable components to compensate for antenna detuning due to loading from nearby external objects, may adjust transmit power levels, and may make other wireless circuit adjustments.
