Antenna tuning control system
摘要:
A device for optimizing antenna operation comprises a wireless control signal detector for detecting a wireless control signal generated by a remote control unit, and a microprocessor operatively connected to the detector. The microprocessor is programmed to analyze the wireless control signal during a learning operation to determine a coding format of the wireless control signal and to analyze the wireless control signal during a normal use operation to determine a broadcast channel or station selected by a user. The device additionally comprises a plurality of tuning elements operatively connectable to an antenna for tuning the antenna, and a plurality of switching circuits operatively connected to the tuning elements and to the microprocessor. The switching circuits are operable to selectively couple the tuning elements to the antenna, in response to signals from the microprocessor, thereby optimizing signal reception by the antenna for a channel or station selection encoded in the wireless control signal.
