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 display in a housing with a metal wall. An antenna may have an antenna ground formed from the wall and an antenna resonating element. Transceiver circuitry may be coupled to an antenna feed that extends between the antenna resonating element and the antenna ground. A return path may extend between the antenna resonating element and the antenna ground in parallel with the feed. The antenna resonating element may have segments that are coupled by a frequency dependent filter. At a first frequency, the filter may have a low impedance so that the antenna resonating element has a first effectively length. At a second frequency that is greater than the first frequency, the filter may have a high impedance so that the antenna resonating element has a second effective length that is shorter than the first effective length.

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.
