Patent abstract
An electronic device provides a detuning monitor circuit configured to detect a change in a voltage standing wave ratio (VSWR) between a radio frequency (RF) transmitter and an RF antenna relative to a predetermined VSWR baseline and a proximity detector circuit configured to adjust transmission power of a carrier wave transmitted from the RF transmitter, if the change fails to satisfy an acceptable VSWR condition. Network proximity detectors are also provided to allow coordination of antenna subsystems to comply with specific absorption rate (SAR) constraints and/or maintain/improve antenna performance.
