    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.

    Abstract: A radio frequency device has a multifunctional tuner that stores measurements of reflection coefficient parameter in a register. The radio frequency device also has a transceiver that has a transmitter. The transceiver may detect a transmitter signal from the transmitter to an antenna in an initial tuning state and then determine whether the transmitter signal is stable. In response to the transmitter signal being stable, the transceiver may measuring the reflection coefficient parameters at the multifunctional tuner. Furthermore, the radio frequency device has a baseband controller that has a memory to store instructions and a processor to execute the instructions. The instructions cause the processor to determine an antenna impedance based on the reflection coefficient parameters, and in response to determining that the antenna impedance is greater than or less than a threshold antenna impedance, iteratively tune the antenna using the multifunctional tuner.

    Abstract: An electronic device may include control circuitry, sensors, and wireless circuitry having antennas. The sensors may generate sensor data that is used by the control circuitry to identify an operating environment for the device. The sensor data may include a grip map generated by a touch-sensitive display, infrared facial recognition image signals or other image signals, an angle of arrival of sound received by a set of microphones, impedance data from an impedance sensor, and any other desired sensor data. The control circuitry may use the sensor data, radio-frequency spatial ranging data, information about whether audio is being played over an ear speaker, and/or information about communications protocols in use to identify the operating environment. The control circuitry may adjust antenna settings for the wireless circuitry based on the identified operating environment to ensure that the antennas operate with satisfactory antenna efficiency regardless of operating conditions.

    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.

    Abstract: An electronic device may be provided with a housing. The 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 a slot. An antenna feed may have a positive antenna terminal coupled to the peripheral metal member and a ground terminal coupled to the ground and may feed both an inverted-F antenna structure that is formed from the peripheral metal member and the ground and a slot antenna structure that is formed from the slot. Control circuitry may tune the antenna by controlling adjustable components that are coupled to the peripheral metal member. The adjustable components may include adjustable inductors and adjustable capacitors.

    Abstract: In some implementations, the disclosed techniques may include tuning a first antenna element to a first tuning state during an acquisition mode for establishing communication channels with satellites. The first tuning state can configure the first antenna element to receive signals in a first frequency range. The techniques may include establishing the communication channels using the first antenna element in the first tuning state during the acquisition mode. The techniques may include transitioning from the acquisition mode to a tracking mode. The techniques may include changing the tuning state of the first antenna element. The techniques may include determining a location of the mobile device during the tracking mode: (1) using the first antenna element and a second antenna element of the mobile device or (2) not using the first antenna element and using the second antenna element that is configured to receive signals in a second frequency range.
