    Abstract: Electronic device antenna structures may include first and second antennas. A housing may have a periphery that is surrounded by peripheral conductive structures such as a segmented peripheral metal member. A segment of the peripheral metal member may be separated from a ground by an opening. An antenna feed for the first antenna may have a positive antenna terminal coupled to the peripheral metal member and a ground terminal coupled to the ground. A return path for the first antenna may span the opening in parallel with the antenna feed. A plastic carrier may be mounted to a printed circuit and a metal housing structure using screws. The plastic carrier may support an antenna resonating element for the second antenna and may support the return path for the first antenna. The screws may short metal structures on the plastic carrier to the metal structures and traces on the printed circuit.

    Abstract: An electronic device may be provided with wireless circuitry. Control circuitry may be used to adjust transmit power levels for wireless signals, may be used to tune antennas, and may be used to adjust other settings for the wireless circuitry. The electronic device may have a coupler interposed between an antenna and wireless transceiver circuitry. The coupler and a receiver within the transceiver circuitry may be used to make measurements on tapped antenna signals such as transmitted signals and signals reflected from the antenna. By analyzing the tapped antenna signals, S-parameter phase and magnitude information may be gathered that provides insight into whether the electronic device is operating properly and whether an external object is adjacent to the antenna. If an external object is present, the electronic device may limit wireless transmit power and may adjust tunable components in the antenna to compensate for detuning from the external object.

    Abstract: Electronic devices may include antenna structures. The antenna structures may form an antenna having first and second feeds at different locations. Transceiver circuitry for transmitting and receiving radio-frequency antenna signals may be mounted on one end of a printed circuit board. Transmission line structures may be used to convey signals between an opposing end of the printed circuit board and the transceiver circuitry. The printed circuit board may be coupled to an antenna feed structure formed from a flexible printed circuit using solder connections. The flexible printed circuit may have a bend and may be screwed to conductive electronic device housing structures using one or more screws at one or more respective antenna feed terminals. Electrical components such as an amplifier circuit and filter circuitry may be mounted on the flexible printed circuit.

    Abstract: An electronic device may be provided with wireless circuitry. The wireless circuitry may include an antenna. The electronic device may have a housing in which control circuitry and radio-frequency transceiver circuitry is mounted. The transceiver circuitry may be used to transmit and receive radio-frequency signals with the antenna. The housing may have a housing wall with a locally thinned portion aligned with the antenna. The antenna may have a sheet metal layer attached to a plastic cavity with a layer of adhesive. Recesses in a printed circuit may receive prongs formed from a sheet metal layer. The plastic carrier may have cavities separated by ribs. The sheet metal layer may form a planar inverted-F antenna resonating element, a ground plane, a return path between the resonating element and ground plane, and a feed path that extends along one of the ribs and into an opening in the printed circuit.
