    Abstract: An electronic device may be provided with wireless circuitry that includes one or more antennas and a transceiver. An integrated circuit may be coupled between the transceiver and the antenna and may include multiple tunable components such that tune the response of the antenna. The control signals may be generated by a tuning controller external to the integrated circuit. Shared control interface circuitry may be formed on the integrated circuit for interfacing between the tuning controller and each of the tunable components on the integrated circuit. The control interface circuitry may include a conductive path and decoupling circuitry that routes the control signals to corresponding control inputs on each of the tunable components. Sharing the control interface circuitry between each tunable component on the integrated circuit may minimize the space required on the integrated circuit for controlling the response of the antenna.

    Abstract: An electronic device may be provided with wireless circuitry. The wireless circuitry may include one or more antennas. An antenna may have an antenna feed that is coupled to a radio-frequency transceiver with a transmission line. An impedance matching circuit may be coupled to the antenna feed to match the impedance of the transmission line and the antenna. The impedance matching circuit and tunable circuitry in the antenna may be formed using integrated circuits. Each integrated circuit may include switching circuitry that is used in switching components such as inductors and capacitors into use. Sensors such as temperature sensors, current and voltage sensors, power sensors, and impedance sensors may be integrated into the integrated circuits. Each integrated circuit may store settings for the switching circuitry and may include communications and control circuitry for communicating with external circuits and processing sensor data.

    Abstract: Electronic devices may include antenna structures. The antenna structures may form an antenna having first and second feeds at different locations. A first transceiver may be coupled to the first feed using a first circuit. A second transceiver may be coupled to the second feed using a second circuit. The first and second feeds may be isolated from each other using the first and second circuits. The second circuit may have a notch filter that isolates the second feed from the first feed at operating frequencies associated with the first transceiver. The first circuit may include an adjustable component such as an adjustable capacitor. The adjustable component may be placed in different states depending on the mode of operation of the second transceiver to ensure that the first feed is isolated from the second feed.
