ABSTRACT:
A tunable receiving apparatus, includes a variable capacitative member, a tunable antenna having a resonant frequency controlled by the variable capacitative member, a tuner outputting a control signal related to a receiving-sensitivity of the tunable antenna, and a control circuit processing the control signal and controlling the variable capacitative member. The variable capacitative member is controlled automatically by the control circuit to optimize the receiving-sensitivity.
