Abstract
A communication device (100) including an antenna (110) for receiving a signal. A receiver circuit (12) is coupled to the antenna (110) and demodulates the signal which is received by the antenna (110). A signal strength measuring circuit (126) is coupled to the antenna (110) and generates a signal strength indicator signal representing a strength of the signal received by the antenna (110). A controller (130) is coupled to the receiver circuit (120) for receiving the signal strength indicator signal and generating a tuning signal in response thereto. An antenna tuning circuit (140) is coupled to the controller (130) and is responsive to the tuning signal for tuning the antenna (110) to a reduced gain level when the strength of the signal received by the antenna (110) is indicative of strong signal conditions.
