Antenna with integrated proximity sensor for proximity-based radio-frequency power control

摘要: An electronic device may have a housing in which an antenna is mounted. window be mounted the to allow radio-frequency signals transmitted from and receive signals. Near-field radiation limits satisfied by reducing transmit power when external object detected vicinity of dielectric antenna. A capacitive proximity sensor used detecting objects The formed using integral resonating element capacitor electrode structures. These structures identical first second patterned conductive layers on opposing sides substrate. transceiver coupled through respective high-pass low-pass circuits.
