Electronic Device Having Sensors and Antenna Monitor For Controlling Wireless Operation

摘要

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.

主权项

1. An electronic device, comprising:
an antenna; wireless radio-frequency transceiver circuitry that transmits radio-frequency signals through the antenna; a tunable component that tunes the antenna; a connector that is configured to receive an external connector; and control circuitry that tunes the tunable component to tune the antenna based on information about use of the connector.
